Years before Thomas Jane played a sex-obsessed gigolo on "Hung" ... he played a sex-obsessed woman who was obsessed with humping closet doors -- but no one ever saw the footage ... until now.
It all went down at the L.A. home of Jane's ex-GF Melinda Hill back in 1998 ... when the two aspiring actors were goofing around and decided to make a "crazy" improv movie ... which they shot with a VHS camera.
In the "flick," Jane plays a delusional woman who's constantly posing for photos ... even though no one's taking her picture. There's a lot of gyrating and hip thrusting ... followed by a death scene.
But Jane isn't embarrassed ... in fact, he openly reminisced about it during a recent interview with Jillian Lauren and ex-GF Melinda during the launch of "Eat My Podcast."
Jane was under the impression the footage had been lost years ago ... turns out, he was wrong.
