Another bumper edition of Filmism news this week, starting with the revelation-that's-really-no-surprise about Lindsay Lohan going to the clink for 30 days after violating parole from her 2007 drug arrest.

In the midst of Mel Gibson's custody battle it emerged his agency had dumped him, but contrary reports it was about money tussles rather than his liberal use of the 'n' word.

John McTiernan has pled guilty to lying during the Anthony Pellicano wiretapping case, and Swiss authorities have said they won't extradite lauded director/unconvicted child rapist Roman Polaski to the US.

But the weirdest news is that Hayden Christensen has sued USA Network, saying they stole his idea for a TV show. At least he can feel safe knowing nobody will rip off his acting style.

In film news, Avatar's returning to screens with eight minutes of extra footage soon, and the next Mission Impossible is a go. After the box office from the dire Knight and Day, Tom Cruise will need a hit – he's been on the verge of a backlash by Hollywood for years, with only his star pulling power keeping him afloat.

US Congress has quashed the possibility of an exchange trading box office futures. I think I could have made money on that! Miramax has not been sold back to the Weinsteins as we reported a few weeks back, but looks like it's being taken over by an American construction magnate.

We said goodbye to Harvey Pekar, the real-life subject of 2003s warm-hearted, funny American Splendor (also played by Paul Giamatti), and Ed Norton's been fired from the role of the Hulk in the upcoming Avengers movie, reportedly for not playing nice.

I've got huge respect for Norton's talent, but I've heard rumours like this before. In Creative Screenwriting's podcast of the hilarious poker mockumentary The Grand, writer Zak Penn talked about being none too happy with Norton changing everything about his script for 2008's The Incredible Hulk.
