Tom Cruise Circling One Shot: Welcome To Horrendous Idea # 756,243
Reacher is also a hell of a physical specimen -- in the books, he's 6'5" and 250 pounds of highly-trained trouble, and casting him seems like a seriously (ahem) tall order. The film is being developed by Christopher McQuarrie, and of course, the logical choice for Reacher is...
Wait, what? How did we go from towering badass to 5'7"-in-heels-on-a-ladder chicklet-mouthed lunatic? Don't get me wrong, I like Cruise as Ethan Hunt... well, not counting M:I2, but casting him as Jack Reacher would be the mother of all casting fuckups. This is one of those instances where the look of the character is integral to the piece. This isn't casting someone who's blond to play a brunette. Cruise may be a capable actor, but there's no possible way he can pull off "intimidating giant."
It's just early rumor at this point, so let's all pray that this never come to pass.
