I didn't realize he/she was in that

Jessica Chastain was the pregnant neighbor in an episode of Veronica Mars.

 

Fallon also had one scene in a "Band of Brothers" episode as the guy who brings Easy Company a jeep load of ammo right before they go into Bastogne.

 

The Fallon scene in Almost Famous was the best thing he did before becoming a talk show host.

 

The lady who played Roz also appeared on Cheers. She was a reporter interviewing Woody when he was running for city counsel. One of the last 5 episodes or so.

That's funny about Mahoney in Cheers. Also, I vaguely remember Frasier telling his bar pals that his parents were both shrinks.

 

Some off the top of my head: Hank from Breaking Bad chasing Tom Cruise in the Firm. (The Jonathan Banks pull earlier from Airplane cracked me up). Laura Palmer's mom and Donna's dad in Twin Peaks reunite in Seinfeld as Susan's parents. David Letterman in Cabin Boy 'Don't Eat the London Broil.' Remember the old Heinz commericial? Joey from Friends places the bottle on the edge of a building, walks down a few flights of stairs, buys a hot dog, says, "I got it covered." God, I hated that commercial.

 

Hank was also in "Starship Troopers" as the base commander during the early Earthbound training sequences.

 

I saw the very end of Kicking and Screaming on TV today and the little kid who played Will Ferrell's son was Josh Hutcherson, AKA Peeta from The Hunger Games.

 

Noticed a couple in the last few months, both from John Hughes movies:

Louie Anderson in "Ferris Bueller"
John Cusak in "Sixteen Candles"

EDIT: Oh, and in addition, I recently watched "One Flew over the Cuckoo's Nest," and saw the guy in my avatar, Christopher Lloyd, as one of the patients in the institution. Read online that it was Lloyd's first film role.

 

Joan Cusack was also in Sixteen Candles as the chick with the neck brace.

And I had forgotten Anderson was in Ferris Bueller as the flower delivery guy.

 

My local NBC affiliate KSBY is based in San Luis Obispo, and in the newsroom we put on their 6 p.m. newcast everyday. One of their anchorpersons is John Reger, who is pretty good as far as small-market news readers go. Here's his bio

So, we're watching the newcast Friday and notice Reger isn't working that night. Near the end of the program, they play a video about Reger's news career, and then talk about how before he got into TV news, he had a bit of an acting career. They go over all his small TV guest shots, bit parts in movies and a singing career that had him performing on "Star Search." And then, one particular movie title is mentioned, and my ears perk up. Turns out this guy who's been giving me my local news for the past few years is the same guy who played egostistical German skiier Rudi Garmisch on one of my favorite Skinemax guilty pleasures "Hot Dog: The Movie."

Now, back to that video: with the whole career retrospective thing and the borderline tribute, I'm thinking Reger must have quit or suddenly got laid off (which is common in this business). Nope, they go to him on remote, and it turns out he's in Colorado to attend a cast reunion to celebrate the 30th anniversary of "Hot Dog's" release.

Man, I just found it so hilarious that the guy who I remember uttering such classic lines as "Do you know what I had for breakfast this morning rookie? How do you say... I had Sonny side up, und I had Sonny side down, und I had Sonny side all ze vay around" is a local newscaster in my area 30 years later.

 

Stay out of zee meedle! Yes. Chinese Downhill! It is zee only way.

 

I was just thinking about "Hot Dog" the other day because I always get it mixed up with "Ski School," which Jimmy Fallon was referencing when he presented his own version of the NHL awards.
