Cuba Gooding, Jr. played O.J. Simpson in the upcoming 'The People vs. OJ Simpson,' but he says his head is spinning with so much info he still can't figure out if O.J. did the deed.

We got Cuba outside the Westwood Village Theatre where the series was screened. Cuba also said he stands by the Motion Picture Academy.

As for O.J. ... Cuba needs to check out the trail of blood from the bodies to O.J.'s bathroom. And about 50,000 other pieces of evidence.
