Night at the Museum was a crappy movie but after making over $500 million worldwide, a sequel was always going to be on the cards. It looks like it might be sooner rather than later too as Dark Horizons are reporting that writers Thomas Lennon and Ben Garant are about to begin work on writing another 'museum coming to life at night' adventure. The duo also wrote the original movie and since then they've seen their scripts Reno 911: Miami (they created the cable show too) and the upcoming Balls of Fury turned into feature films. Both Ben Stiller and Robin Williams are both said to be signed up for a return also but not director Shawn Levy at this point. Levy and the screenwriters struggled to flesh out enough idea's to keep one Night at the Museum interesting (actually the script was so dumb they made the whole story develop over a couple of days rather than one night!) so a sequel seems like a mountain they might struggle to climb without re-doing the first movie all over again. Take your money from the first movie and run is what I say.
