March is a great month for people who like things en masse.  There's March Madness, of course, for fans of college basketball.  There's SXSW for lovers of movies and/or music.  And for the TV geek, there's PaleyFest.  This year's line-up features a metric ton of panels for The Walking Dead, True Blood, White Collar, Hot in Cleveland, Parks & Recreation, Eastbound & Down, Supernatural, American Idol, Community, Glee, and Raising Hope.  But the big draw has to be "An Evening with Jimmy Fallon."  Wait -- that can't be right.Oh, no it's the combined Freaks & Geeks/Undeclared panel moderated by Judd Apatow.  Those shows launched more than their share of careers, including Seth Rogen, Jay Baruchel, and Jason Segel -- all official guests.  Freak James Franco isn't listed, but given how busy he likes to keep, my fingers are crossed for a surprise appearance as one of the "additional members of the casts & creative teams."PaleyFest 2011 unfolds March 4-17 at the Saban Theatre in Los Angeles.  Hit the jump to see the full list of panelists.Buy your tickets here.Opening Night: The Walking Dead (Friday, March 4 at 7:00 p.m.)Moderator: Mike Schneider, LA Bureau Chief, TV Guide Magazine
