I just discovered this film recently by accident...it's ROLLER BOOGIE from 1978, methinks, so the outfits and hair are AMAZING (lots of vintage Gucci!). PLUS, it was shot in Venice Beach (California), which is cool to see. It hasn't changed too too much. Though there are some places in the film that are ghetto-ish back then...and now they all have multi-multi-million-dollar homes (especially when you see them skating around the canals).
It's worth a watch. It's not really painful at all. Especially if you love 70s fashion! And if you are a fan of Xanadu, you will LOVE it!!!♡
