First, the bad news: tonight’s episode of 30 Rock is a rerun. The good news came earlier this week, on Tom Hanks’s Twitter feed: “RadioMan delivers msg from T.Fey. Result? I’m on 30 Rock! Thanks, RMan Hanx.” Translation: “RadioMan” is Craig Castaldo, a homeless man who frequently pops up in New York-filmed TV shows and films, and is often found outside of David Letterman’s studio. Fey posed for a picture with Castaldo last week, and he apparently somehow brokered the deal for Hanks to make a 30 Rock guest appearance.
30 Rock fans often split on the show’s frequent use of guest stars; some say they’re too reliant on them, while others insist that Fey and her writing staff often find ingenious ways for celebrities to send up their own images or bring their comedic gifts to off-the-wall characters. We lean towards the latter point-of-view (with occasional exceptions — even we weren’t nuts about Jennifer Aniston’s episode). So with an eye on the upcoming Tom Hanks cameo, we took a look back at some of our favorite 30 Rock guest appearances. In the interest of brevity, we restricted ourselves to folks who only appeared once, so you’ll not find recurring favorites like Will Arnett’s Devon Banks, Jon Hamm’s Dr. Drew Baird, or Isabella Rosellini’s Biana Donaghy (“You know I love my big beef ‘n’ cheddar!”). Check out our picks after the jump, and add your favorites in the comments.
