Foxx was good in The Soloist, even if the movie was obvious Oscar bait. He won the Best Actor award for his Ray Charles impersonation, one of the few times in the past 15 years I've even kinda-sorta agreed with the Acadaemy's pick. His acceptance speech was great — [paraphrasing] "I got my first acting lessons from my grandmother, who told me to act like I had some sense."
I don't see how he could possibly make a Tarantino flick any worse.
