The Wonder Years was a defining series for many of its cast members (both young and old), with many of them going on to do the best work of their careers after it ended in the early '90s. Its critically acclaimed storylines about the waxing of a certain time of youth allowed for a variety of actors to look back on it with fondness, not to mention confidence in its quality and influence.

Fans may not have kept up with the lives of Fred Savage, Danica McKellar, Jason Hervey, and the rest but both after the series ended and during its filming, they were involved with all sorts of unlikely projects. Some cast members largely retired from acting after the series came out, but some like Savage continue to pop up in the most unlikely of places.

Danica McKellar - Hallmark Movies

As cute and engaging as Winnie was, Danica McKellar has made even more of an impact as a charismatic adult in feel-good movies for Hallmark. Since the mid '00s, she's become one of the most prominent actresses to appear on the Hallmark Channel, especially in its Christmas movies.

Fred Savage - Friends From College

Fred Savage appropriately took on the role of Max Adler in Friends From College, a Netflix original series that explores the bond of a tight-knit group of friends after they reconnect on the cusp of their forties. In many ways, the role seemed like an adult Kevin Arnold, and the series touches on adulthood with the same thought-provoking authenticity as The Wonder Years.

Savage has mostly been involved with directing and producing, preferring to be behind the scenes than in front of the camera. Fans will also have heard him lend his impressive voice talents to dozens of characters in Family Guy, American Dad, and more.

David Schwimmer - Band of Brothers

While most fans of David Schwimmer would immediately recognize him as Ross on Friends after playing one of Karen's hip, motorcycle riding boyfriends, he also starred in the Steven Spielberg and Tom Hanks produced Band of Brothers alongside Michael Fassbender and Damien Lewis as Captain Sobel.

Schwimmer received critical acclaim for his role as a tough military officer who ended up cowering in the face of adversity, constantly upstaged by the bravery of the officers under his command. Lately, he's been appearing in British television, in comedies like Come Fly With Me and Intelligence.

Daniel Stern - City Slickers

He also starred in another '90s gem alongside Billy Crystal and legendary character actor Jack Palance, City Slickers.

He was different than the boys she usually spent time with, and added a different perspective to the series given his home life.

Ribisi recently starred in his own television series called Sneaky Pete, this time playing another Pete who is a reformed con man (with the real name Marius) trying to make a better life for himself. Ribisi also signed on for every film so far in the Avatar franchise.
