The man filing the lawsuit is Tom Huang -- who once wrote an episode of "The Mullets" back in 2003.

According to legal documents, Huang claims he came up with an idea for a movie back in 2004, wrote a "treatment" for it ... and talked it over with his agent Brad Kaplan.

But in the lawsuit, filed Wednesday in L.A. County Superior Court, Huang claims Kaplan "stole" the idea and gave it to one of his clients named Erik White .. who went on to write and direct "Lottery Ticket."

Huang claims "Lottery Ticket" ripped off all sorts of elements from his movie -- including "detailed plot elements, characters, and scenes." Huang is suing for an undisclosed amount -- but states in the lawsuit that he believes "Lottery Ticket" will rake in millions ... so it's safe to say he's gonna want a ton of cash.

According to documents just filed in federal court in California, a judge ruled that the "Bruno" scene didn't have enough in common with a scene from an unmade movie called "Himbos" ... in which some dude was also supposed to don a Velcro suit and wreak havoc at a fashion show.

Levitt -- who ended up getting 31 stitches in his arm -- posted

on Sunday ... shot moments after he slammed his bike into the back of a taxi cab while filming a movie called "Premium Rush" in New York.

Sources close to the production tell us Vince met Lindsay while the two were in Cannes back in May ... in between Lindsay's doomed court appearances with Judge Revel.

We're told Vince offered Lindsay a role in his movie "Underground Comedy Movie 2010" -- in which she plays a gun-toting Marilyn Monroe spoof who shoots at the paparazzi.

Lindsay accepted the role -- even though it entailed filming on June 17 ... while LiLo was still wearing her SCRAM bracelet around her ankle.

We're told Lindsay was cool with the SCRAM being in the shot ... and even ad-libbed a line referencing the device.

With a facial expression appearing like she saw a reflection in the mirror of what she was wearing, former actress Mischa Barton exited a London pub on Wednesday ... in some sorta apron/wrap bikini top cut-out dress thing.

Where are those high-waisted yellow banana pants when you need them?

TMZ has obtained never-before-seen photos of the Jackson house in Encino, CA where Katherine Jackson and her grandchildren live -- and according to our sources, it was personally decorated by Mama Jackson herself.

Katherine definitely has a flair for pretty things -- but we can't help but raise our eyebrows at that creepy toy display case.

Thanks to Michael Jackson's Secret Vault for the pics.
