It's nearly impossible to think an actor besides John Krasinski playing the role of 'Jim Halpert' on the American version of "The Office," but it may not have happened without the help of Matt Kenseth.
Did that just blow your mind? It should have.
Back in 2002 -- a full three years before the NBC premiere of inarguably the greatest comedy series of all time, in my opinion, at least -- a fresh-faced Krasinski appeared in a commercial with Kenseth that caught the eye of future "Office" executive producer, Greg Daniels.
The back-and-forth dialogue between last fall's grand marshal at Texas Motor Speedway and Kenseth (more back than forth, knowing the stoic Joe Gibbs Racing driver) and wild antics by the now-36-year-old led to an audition and before long, "Jim" was born.
Krasinski recently spoke about it on NPR's Fresh Air podcast with Dave Davies.
"I haven't seen or heard that since the time I did it. That is a real send back to memory lane," Krasinski said. " … That was a huge performance and I remember we had a little bit of script and Matt Kenseth had said he doesn't want to have a line in the script. He was very shy and he didn't want ... he just wanted to walk through the commercial.
"At the end of the day, they just asked 'Would you just improv and have fun? Let's see what we get' and we just kept going and I think they just watched the dog go off the leash, just improving all this stuff. By the end, Matt said 'Well, now I do want to say some stuff.' So he came in and we were joking around all day. It was probably one of the more fun times I've had, certainly before I got 'The Office.' "
The commercial worked wonders for both men, as Krasinski is now a household name and Kenseth won five races that year, following it up with his only premier series title the following season.
