Cute woman in nice car, chats to boyfriend who pumps gas. They arrange to meet up, but shock, horror, she drives into a giant. A prehistoric giant. Thankfully her boyfriend and father discuss over her head and agree she's probably wrong, patriarchy rules ok. His hair is completely ridiculous, and he looks like a bonus chromosome kid.
They go up in a helicopter to try and spot him, there is an awfully long scene of helicopter shots. Her father finds the giant and begs for his life. We cut quickly to a swimming pool scene with bonus c/some kid is singing in a richie valens/teen angel kinda way. This song goes on and on. Make it stop.
The kids are going out to find Daddy, he's got a dune buggy and so now we get some garage surf music. She appears to be having an orgasm as they go over the sand in his water filled tyres. This scene also goes on for some time.
They decide to get some rest, so it's obviously time for another painful song, which has full backing band except it's just him out in the desert. Mind. Blown.
they find her fathers camera, pouty c/some boy decides they need to look in the next ravine, cue more shots of dune buggy drives. sigh. He really is a whiny little fuck.
Plus side, Roxy (the chick) is carried off by the prehistoric giant, and taken back to his cave - where her father is. Ahhh, sweet. Our giant appears to have electric spot lighting, and is thoughtfully checking Roxy for lice. Caring. Roxy shaves her father and the giant. That was unexpected. There are a number of shots of native lizards, so it's kinda a bgrade movie, with porn, for me.
They escape. Giant pissed. Rampage. Cops. Swimming pool and more bad music.
As I said, bonus chromosome (this is his general look throughout the movie)
And the trailer
And because I'm vindictive, here's 90min of campy giant fun. There's also a MST3K version around...
