Ben Stiller hasn't made an awful lot of good, even decent, movies lately. But he's an excellent director and still a funny guy as both The Cable Guy and Tropic Thunder will attest to.
 

But if Ben Stiller has made a comedy classic then it's undoubtedly Zoolander, and he's been talking to Empire Magazine about the proposed sequel: "Where it’s at is we've completed the script, Justin Theroux (the DJ in the first film) and I, and handed it into the studio," he told the magazine "Now the studio has the script and we’re at that point where we’re waiting to see what they want to do. It’s ten years later and most of it is set in Europe. I don’t want to give away too much, but it’s basically Derek and Hansel ten years later - though the last movie ended on a happy note a lot of things have happened in the meantime. Their lives have changed and they’re not really relevant anymore. It’s a new world for them. Will Ferrell is written into the script and he’s expressed interest in doing it. I think Mugatu is an integral part of the Zoolander story, so yes, he features in a big way."
 

Ferrell had a supporting role in the original really before he blew up as a comedy star in his own right, so if he did come back there would have to be a lot more for him to do. "You can dere-lict my balls" Sorry.
