Since medicine first started to become formalized thousands of years
Chad Michael Murray: The One Tree Hill actor got an early start on GG as bad boy (who was crushin’ on Rory) Tristin Dugray.
Adam Brody: I first fell in love with Adam on Gilmore Girls and was deeeelighted to see him then move on to my next TV love, The O.C.. (Fun fact: On GG, Adam’s character, Dave Rygalski, actually moves away to California!)
Krysten Ritter: I love Krysten Ritter’s other roles in Veronica Mars, Breaking Bad, and Don’t Trust the B—but, I have to admit, I was not a huge fan of her as Rory’s new college friend Lucy.
Seth MacFarlane: The Family Guy creator had a brief (but memorable) role as cranky Bob, one of Lorelei’s classmates.
Billy Burke: Before he was Bella’s dad in the Twilight franchise, his character Alex Lesman dated Lorelei. (Note: I couldn’t find a clip of him online, but here’s one of Lorelei talking about going on a fishing date with him…)
Victoria Justice: The Nickelodeon’s stars first acting credit was as “Jill #2” on Gilmore Girls. Her scene acting against Melissa McCarthy is a memorable one:
Jane Lynch: I’d list all the ways you know/recognize Jane Lynch, but… well, you know who she is. She had a one-episode cameo as a nurse on GG in 2000.
Ron Swanson played Jackson’s slightly train wreck-y brother on Gilmore Girls and he hit on Lorelai, because of course he did. It’s admittedly pretty hilarious.
The future Schmidt played one of Dean’s drunken friends during his bachelor party before his wedding to Lindsay.
