need help finding caveman movie
I know the movie i am looking for is not "one million BC" or "Caveman" with Ringo Star. In the movie I am looking for they were on a beach at the end and a massive tidal wave was coming. Some characters escaped on a raft at the end. Also there was a weird part where a girl thought she was leaning against a rock but it turned out to be a nasty leech like monster. Please help me find this movie.
I would also like to take time to reccomend the movie "Dinosaurus". It takes place in modern day but there is a caveman and some sweet dinosaur battle scenes. Cheers.
