Actress Halle Berry was in Mexico City on Thursday (April 19) for the premiere of her new thriller "Perfect Stranger". Berry plays a news reporter caught up in a murder investigation in the film, which also features "Die Hard" star Bruce Willis. "Yes I think the name is very reflective, it's a suspenseful, sexy thriller, so yeah I'd say yes," Berry said. The 40-year-old star won her Oscar for best actress playing a down-on-her-luck waitress in 2001's "Monster's Ball". The twice-divorced Berry is now dating model Gabriel Aubry, who is 10 years her junior. "Perfect Stranger" opened at No. 4 in the United States early this month with 11.5 million U.S. dollars.
