From the blog Mike Sragow Gets Reel:
Industry pundits have been comparing the potential impact of
doing a bit part as a Thailand-based tattoo artist in "The Hangover 2" to the spectacular cameo of
as himself in "The Hangover." I think the only way a Gibson bit could work is if the filmmakers spent whatever money they have left in their budget to make a tell-all
and release it first.
After all, it was
's "Tyson" that paved the way for audiences' acceptance of Tyson in "The Hangover." Toback's incisive, empathetic documentary wasn't an account of redemption; the documentary itself was Tyson's redemption.
