According to E! Entertainment News--the only information source that matters, if you're really, really stupid--Josh Duhamel is "not sure" he'll be back for the latest Transformers movie.
I think I speak for all Americans when I say, "Who's Josh Duhamel?"
Since I have cable TV, I've seen huge chunks of the Transformers movies, and all I remember are giant but weightless CGI robots, plenty of offensive caricatures and Shia The Beef running around screaming, "OPTIMUS!" Whoever Josh Duhamel is, he clearly made no impression on the films whatsoever.
Then again, I'm pretty sure he's made no impact on anybody whatsoever. I'd be willing to bet that if you asked ten random strangers who Josh Duhamel is, none of them would know. Some of them might say, "Yeah, wasn't he the guy in Pearl Harbor who was even less interesting than Ben Affleck?" and while that was my first thought, too, it turns out that particular nonentity was Josh Hartnett, who has himself gone from being hyped as The Next Big Thing to toplining direct-to-video horror movies, a career arc that should surely give pause to Duhamel.
What I'm saying is, Josh Duhamel should be fighting like hell to continue doing whatever minimal, uninteresting work he can get in a new Transformers movie because hey, a paycheck is a paycheck, and I'm guessing a check from a shitty Michael Bay movie has more zeroes in it than a check from some celebrity autograph fest. Sure it may be humiliating to find yourself billed below the guy who does the voice of Optimus Prime, but it beats sitting between Billy Mumy and Jonathan Frid at a table in some suburban convention center, with a placard in front of you identifying you as a "former Transformers star" and gritting your teeth the whole time because Mumy's got a huge line in front of him and you're just sitting there.
And he deserves it, dammit, because Billy Mumy recorded Fish Heads and you...well, you're just Josh Duhamel.
