Robert De Niro's acting skills have been bought into question by his The Deer Hunter co-star Meryl Streep, who reveals the movie great is terrible at charades. Streep is among the stars who attend a top secret celebrity charades party in New York City every Christmas and she admits no one wants to find themselves on the same team as "shy" De Niro. The actress, who likes to partner with her The Devil Wears Prada co-star Stanley Tucci at the bash, admits, "He's (De Niro) so bad. He knows... He's very shy." But Tucci is quick to point out that Streep is one of the best three charades players at the star-studded party. He explains, "The three best players are Meryl, STEVEN SONDHEIM and MIA FARROW."
