Cruise has had a few good roles over the years -- such as A Few Good Men -- but for the most part his resume is chock-a-block full of Hollywood popcorn. And the thought of Days of Thunder makes me cringe.
On the upside, I suppose Cruise's height will come in useful should he need to climb into a GT40 for a scene.
How tall was Carroll Shelby, anyways? Approx. 6ft. 3in.? More?
According to IMDb, Tom Cruise is only 5ft. 7in. and looks nothing like Shelby either.
