The film's dialog is almost entirely in "caveman" language, such as: "aiyee" – help "alunda" – love "bobo" – friend "caca" – shit "gluglug" – drowned "guwi" – out to get "haraka" – fire "kuda" – come "macha" – monster "nya" – no/not "ool" – food "pooka" – broken/pain "ugh" – like "ya" – yes "zug zug" – sex/mate At some showings audiences were issued a translation pamphlet for 30 "caveman words."

Ebert and Gene Siskel both gave the film a negative "don't see it" review on their TV show but softened their criticism somewhat by noting that its dinosaur-related sequences were amusing.
