Wonderful character development!

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

The film makes a home in your brain and the only cure is to see it again.

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

9/10 - Brilliant B-Movie; engaging, charismatic and influential.This is a fun film with genuine thrills to offer. We have a range of stock characters, acted out professionally by a cast battling with the pitfalls of low-production values, working through a simple yet imaginatively dealt with plot, and a monster that gets a lot of screen-time- and deservedly so.The music, composed by veteran composer Paul Dunlap, serves up an aquatic creepiness as well as an effective aid to the shock moments in the film. It is an original and memorable score that has since been echoed in later films.An amphibious monster terrorises the crew of a submerged marine research base. It was clearly inspired by Millicent Patrick's design for the Creature in "The Creature From The Black Lagoon" (Jack Arnold, 1954), but with more ferocious features and a determination for cold blooded murder as opposed to love and self-defence. With regards the monster suit the attention to detail is astounding and almost unbelievable considering some of the models and sets and Ron Burke plays the creature well.The cast of this film do very well considering the dysfunctional props and aforementioned low production values all round. Scott Brady and Gary Merrill deliver every line with the gusto expected from an old horror and Sheree North plays an able and confident member of the crew. The supporting performances from Mike Road, Wende Wagner and John Howard (to name a few) are ably done and James Hong has an early role as the chef – watch Deep Blue Sea (Renny Harlin, 1999) and compare LL Cool J and his parrot to him.This film is compared – often unfavourably- with Howard Hawks' The Thing From Another World (1951) but I would argue that Destination Inner Space is a far more entertaining feature despite its flaws. Lyon's film is ridden with hilarious onset problems that are made entertaining by the cast's refusal to acknowledge any of them, such as Scott Brady's first attempt at getting into his diving gear. These little problems, in my opinion, make the film endearing.It was fashionable in the late 80's to work on underwater films. The figurehead of these films was James Cameron's "The Abyss" (1989); others include "Leviathan" (George P Cosmatos, 1989), "Deepstar Six" (Sean S Cunningham, 1989), Lords of the Deep (Mary Ann Fisher, 1989) and The Rift (Juan Piquer Simon, 1990), as well as later films such as Creatures From The Abyss (Al Passeri, 1994), Proteus (Bob Keen, 1995) and Deep Blue See (Renny Harlin, 1999). Destination Inner Space is, to my knowledge, the earliest horror film to take place in the desolate surroundings of the deep sea, particularly with a scientific/military theme and I would argue that there are elements of this film in the later films.I thoroughly enjoyed what I thought would be a cringe-worthy low budget 60's cheese-fest and came to the conclusion that it is a very entertaining film that harks back to the black and white horrors of the 1950's. It's a shame that this film had such a small budget in a way as it could have been a big success.Well worth a watch and I think in need of a clean-up and subsequent blu-ray release.

I totally enjoyed this 60's slice of deep sea b-movie monster pie. The story was pretty good and engaging, and very weird the way the monster comes to be and both the miniatures and the monster are great! One of the best underwater humanoid sea creatures since Creature from the Black Lagoon. I don't know the history of the creature or who made it, but a lot of time and effort went into constructing that beauty! As a kid I remember it scared the hell out of me because of its size and speed. Not only that, there are a few suspenseful scenes in Destination Innerspace that work really well and I think still hold up today. Sure, the monster is not so scary now, but I'm still very impressed by the look of it which really made this obscure little gem worth finding again.

I know many people will think I'm crazy giving this 7 out of 10 but i really enjoyed this movie so much i had to buy the DVD on ebay.its one of those movies i saw as a kid back in jersey on creature features. the monster looks like the creature from the black lagoons poor cousin. awesome b-movie cast the great Scott Brady playing a good guy for once, Gary Merrill(mysterious island)Sheree north(Kramer's mom on Seinfeld) James hong(big trouble in little china)mike road(voice of race banning on johnny quest)and john Howard(the unknown terror)the plot is somewhat like 1989s deepstar six kind of.there's a flying saucer underwater,and a big green scaly monster with flipper feet.the music is from the b-movie gem the angry red planet(60)its an enjoyable little b-movie. 7 out of 10.

This isn't a B-flick. It's worse, it's a C-flick. Sea-flick? See?Now that my really bad joke is out of the way, I can say this movie is one really bad joke on the audience. To say that the science is flawed is an understatement. (The specimens in the biology lab will die without air?!? They're a sealab; their purpose is to study water-breathing life!) The bombast-filled score is nothing more than stale leftovers from the 1950s, straining at almost every moment to add suspense where none exists. The sets are among the least convincing I've ever seen and the special effects are laughable. The "giant" spaceship and the sealab look like the 12-inch miniatures they probably were. The rubber-suited monster is not scary at all even when poor bluescreen matting makes it look several times larger that life. Worst of all, it commits the cardinal sin that distinguishes truly bad movies from the classics like "Plan 9 from Outer Space," it's no fun. It makes Irwin Allen's "Voyage to the Bottom of the Sea" series look like "Star Wars." Even the eminently forgettable "DeepStar Six" and "Leviathan" were an order of magnitude better than this. It's almost enough to make me rent "Sphere" and finally see the second half. Almost, but nothing's quite that bad.
