BERLIN (AP) -- Jude Law says his biggest challenge in preparing for Steven Soderbergh's new thriller "Side Effects" was psychological: convincing himself that he could play a psychiatrist properly.
The movie has its international premiere Tuesday at the Berlin film festival, where it's one of 19 contenders for the top Golden Bear award. British actor Law plays a psychiatrist who prescribes a new drug he's testing out as part of a lucrative deal with a pharmaceutical giant.
Law told reporters he was faced with "overcoming the reality that I wasn't going to be able to go to medical school in the time it took to prepare for the part."
He added: "I didn't have a huge relationship with pharmaceuticals or an understanding of them."
