After all, what is selling out really? Shades of gray. On one end of the spectrum you have the Eddie Murphys of the world who full-on admit that they don't care how crappy the quality of their acting roles is, as long as they get a big fat paycheck. And on the other end there are the Vincent Gallos, who may as well appear in the dictionary behind the "pretentious dick" entry. The rest is murky territory. However, if Guest's Ivan the Terrible is anything like his turn as the Six-Fingered Man (albeit with a Russian accent, presumably), it may well redeem the Ben Stiller train wreck from unfathomable awfulness. Stranger things have happened.
