Way Back When

We are all obsessed with Channing Tatum -- the guy appeals to men and women alike with his magnetic screen presence and charisma, but back before he was 'Magic Mike' or dancing in those 'Step Up' movies, you might have missed Tatum in these earlier roles.

He launched his career playing the charmingly naive George Michael on 'Arrested Development' and has been making us laugh with roles in 'Superbad' and 'Scott Pilgrim vs. The World.' In today's Way Back When, we take a look at Michael Cera before he was famous.

You know and love him as Ron Swanson on NBC's 'Parks and Recreation,' but Nick Offerman had a ton of roles before he landed the one that made him a household name. In today's Way Back When, we take a look back at Offerman's earlier work.

You know him best for his roles in movies like the 'Spider-Man' trilogy and '127 Hours,' and you can see him next spring in 'Oz: The Great and Powerful,' but in today's Way Back When, we take a look at the early career of James Franco.

You love him as goofball Andy Dwyer on 'Parks and Recreation' (Thursday nights, NBC -- get on it), and you can see him in Kathryn Bigelow's upcoming 'Zero Dark Thirty,' but in today's Way Back When, we show you what Chris Pratt was up to before you knew his name.

Bruce Willis made himself a household name as the ass-kicking John McClane in 1988's 'Die Hard,' and he's been a presence on the big screen ever since. In today's Way Back When, we take you back to a time before you knew Bruce Willis' face.

Thanks to Judd Apatow's films 'The 40 Year Old Virgin' and 'Knocked Up,' Seth Rogen quickly became a face we know and love. In today's Way Back When, we show you Rogen before he was making you laugh on a regular basis.

Jason Segel caught our attention playing lovable goofs with roles on 'How I Met Your Mother' and in Judd Apatow's 'Knocked Up,' but in today's Way Back When, we take a look at one of our favorite actors before he became someone to watch.

We started paying attention to Lizzy Caplan when she played the rebellious and witty Janice Ian in 'Mean Girls' and the doomed Marlena in 'Cloverfield,' and she's been on our radar with her edgy roles ever since. In today's Way Back When, we take a look at some of her lesser-known performances.

We love Alison Brie as the too-adorable Annie on 'Community' and the equally charming Trudy on 'Mad Men,' but in today's Way Back When, we check out what Brie was up to before she hit it big.
