Return To the Lost World was filmed back-to-back with the 1992 version of The Lost World.
In this sequel, the same five people, lead by Challenger return to the plateau where a group has started drilling for oil which is threatening to destroy the land. Gomez has something to do with this. They manage to defeat the drillers and the plateau is saved, much to the delight of the natives.
Like in The Lost World, what few dinosaurs we see are made of rubber and these include a T-Rex and Ankylosaurus.
John Ryhs-Davies and David Warner reprise their roles as Challenger and Summerlee and three of the other actors are also back.
Despite reading several bad reviews of this and those cheap looking rubber dinosaurs, I enjoyed Return to the Lost World.
Rating: 3 stars out of 5.

Every once in a while, a group of friends, with a minimal budget but bags of enthusiasm and talent, will create a low budget masterpiece that takes the world of horror by storm. Raimi and co. did it with The Evil Dead, Jackson and pals succeeded with Bad Taste; and Myrick and Sanchez made a mint with The Blair Witch Project.
Director Todd Sheets and his chums, however, are destined to wallow forever in relative obscurity if Zombie Bloodbath is anything to go by. A lesson in how not to make a cheapo horror, this miserable effort (about a plague of flesh-eating zombiesnatch) serves as a reminder that, whilst many people these days have access to a video camera, most shouldn't take that as their cue to try their hand at making a full-length movie.
It's not that Sheets hasn't got an eye for a nicely framed shot (some of his camera angles and movements are actually pretty good), but rather that a) he has a lousy script b) he has a lousy cast, and c) he doesn't realise that he has a lousy script and cast. Which means that the final film is amateurish in the extreme, and unlikely to be watched in its entirety by anyone other than zombie film completists (like me) or members of the cast and crew (like those who have given the film favourable comments).
Zombie Bloodbath is obviously aimed at undiscriminating gore-hounds, and Sheets (who currently has an incredible 34 titles under his belt as a director) certainly goes out of his way to please, with buckets of offal and blood thrown about at every opportunity. But whilst these moments are undeniably yucky, they aren't particularly convincing, and soon get rather tedious.
So, to summarise, this is a really bad film, with almost no redeeming features. Except for two:
Firstly, it features the single greatest mullet in the history of film, as sported by Jerry Angell, who plays Larry (as well as several zombies). The magnificence of his barnet (coupled with a fetching moustache) is reason alone to watch this film.
Secondly, it has 'pathetic stealth zombies': flesh-eating corpses that lie in wait for unfortunate victims to wander by, before leaping from their hiding place to launch a feeble attack, which requires almost no effort to escape from. Best known for lurking behind a door for hours waiting for someone to open it, 'pathetic stealth zombies' also occasionally hide behind low walls, or sit in churches posing as members of the congregation.
Normally a film this bad would get 1/10 for me, but, in celebration of Jerry Angell's flowing locks, I will generously raise my rating to 2/10.
