When directors need onscreen menace and sheer physical presence, they often turn to giant-sized people. Auditions, chance discoveries and worldwide searches have all proven to be stepping stones for these larger-than-life aspiring actors, but it almost seems that if you can strap on a mask and fill up the screen, whether or not you have talent is often not an issue.
Unfortunately, roles for anyone over seven feet tall seem pretty limited, and giant actors frequently end up typecast as bad guys, hidden behind their masks and costumes (and perhaps moonlighting as professional wrestlers).
