We end the week with all kinds of intriguing possibilities and rumors -- try to contain your joy at the Ghostbusters 3 bit, especially if you're at work. We can't have your employers finding out you're reading Cinematical on the clock!

• Bill Murray is at Fantastic Fest, undoubtedly partying with our writers and promoting City of Ember and at the film's Q&A, AICN's Kraken (a stellar guy) asked the question we all wanted the answer too -- would Murray return for Ghostbusters 3? Murray thinks the scriptwriters (borrowed, you'll remember, from The Office) are off to a good start, that enough time has passed to heal the Ghostbusters 2 wounds, and he would definitely be open to playing Peter Venkman again. In fact, his enthusiasm for the franchise was rekindled by recording the voice for the upcoming video game -- and he had even been singing the theme song in public. There's video of Murray's answer up at AICN, so check it out, and get your hopes up.
  

• One of the questions surrounding Iron Man 2 was its change-up on the writing front. Mark Fergus and Hawk Ostby weren't returning, their job was taken by Justin Theroux, and we all frowned a little inside. But MTV has the scoop that they're unavailable for Iron Man 2 because they're working on something else for Marvel. Fergus wouldn't specify what, he just dropped maddening hints. "There are some really juicy [movies] that we are very much talking intensely with Marvel about ... We're interested in working on a bunch of these other Marvel projections and everything in the Marvel canon is fair game. We have a lot of ideas about all this, but until they officially ask us to come do one of these we'll keep our mouths closed about the actual ideas. It's moving along nicely but nothing official yet. But, yes, we are planning on working on some of those movies. That much I'll say." At this point, all of the Marvel movies have writers -- and impressive ones at that. Either they're replacing someone, or it's a new character altogether. Guess away.

Take from this what you will, but Cinema Blend is reporting on a tip they received from someone who was hanging with Adam Brody in a bar up in British Columbia. What's Brody doing there? Well, apparently some of the cast is with George Miller scouting locations for Justice League Mortal. (Not sure why they'd be up there with the director scouting, but let's roll with it for now ...) Anyway, Brody, Miller and a few others were in a bar, getting wasted, when this girl (who wrote into CB) asked him what they all were doing there. Naturally he said they were scouting for Justice League Mortal (which recently had to shift production from Australia to Canada). Then it gets interesting.

Here's her full quote: "George is our director. He said he's playing The Flash, Common is playing Green Arrow (or Lantern, one or the other), Armie Hammer (sounded like Arm and Hammer) is Batman, someone from "mad max" is Martian Man-hunter (didn't catch the name) and Hayden Christensen is Superman. Brody also nodded to the woman to his right and said "she (he said her name but I didn't catch it) is in it too". Oh, and they had lots of drinks." While I'm very reluctant to believe this one, on the other hand I could totally buy them wanting Christensen to play Superman. He'd bring some more "celebrity" to the cast, even though the fanboys who hated him Star Wars would hate him again -- even more this time -- for Superman. Should be interesting to see this one play out, as Justice League Mortal is supposed to begin shooting this summer.

What do you think about Hayden Christensen playing Superman?
