Sandra Bullock is one of Hollywood's leading ladies, having starred in more than 50 films, and produced several, as well. Once best known for the 1990s films, "Speed" and "The Net," Bullock saw a second wind in her career in the 2000s with the comedy "Miss Congeniality" and critically-acclaimed films including "Crash," "The Blind Side" and "Gravity." In 2010, her versatility and range earned her an Oscar for playing a dedicated mother in "The Blind Side."
