Career: After landing roles in off-Broadway productions, Keitel met Martin Scorsese, an up-and-coming filmmaker, who cast him in his student project before handing him the lead in Mean Streets (1973). Despite an amazing performance, it was co-star Robert De Niro who profited most. Keitel's career took something of a nosedive toward the end of the 1970s, but received a shot in the arm in 1992 thanks to the films Bad Lieutenant and Quentin Tarantino's Reservoir Dogs. This made him hot property, with Keitel going on to star in films such as The Piano (1993), Cop Land (1997), From Dusk Till Dawn (1996) and National Treasure (2004) and its 2007 sequel. He also appeared in the short-lived US version of Life On Mars. More recently, he has starred in Inglourious Basterds (2009), Little Fockers (2010), Moonrise Kingdom (2012) and The Grand Budapest Hotel (2014).
