Fall TV 2009: TV stars pulling double duty

Even a glamorous Hollywood actor needs to shake up the old routine once in a while.

As you've seen from Zap2it's Familiar Faces for Fall TV, actors love to try on new roles. Sometimes, they don't even wait until they're free before taking on another one. Luckily, with the broad TV landscape, they're able to juggle their regular gigs alongside their choice of juicy guest appearances, reality competitions or other challenges.

Here's a look at some of the ambitious small-screen stars pulling double duty and occasionally triple duty during the 2009-2010 TV season.
