Sure, Anthony Hopkins is a brilliant actor, but can he do calculus? According to Variety, he's in talks to star in Miramax's ''Proof'' as a renowned math scholar and the father of the character to be played by Gwyneth Paltrow, who's reprising her London stage role in the movie. He'd shoot in September, then jump to Oliver Stone's ''Alexander,'' where he'll play Ptolemy opposite Colin Farrell's Alexander the Great.
''Proof,'' the 2001 drama that won playwright David Auburn a Pulitzer and a Tony, is about the troubled daughter of a mathematician, a woman who may be just as brilliant -- and as remote from reality -- as her father. Jake Gyllenhaal will costar as Paltrow's love interest. John Madden, who directed Paltrow's Oscar-winning performance in ''Shakespeare in Love,'' will direct.
