Samuel L. Jackson is highest-grossing actor at the box office

Samuel L. Jackson is big news at the box office - his movies have pulled in $7.4 billion during his career.

The actor has appeared in more than 100 movies since his big break in Spike Lee's 1991 movie "Jungle Fever," and his hard work has paid off - he is the highest-grossing actor of all time, according to the Guinness Book of World Records.

Thanks to hits such as "Jurassic Park" ($914 million), "Pulp Fiction" ($212 million) and the "Star Wars" prequels ($2.4 billion), Jackson is top of the Hollywood pile, with his films outstripping the competition at the box office.

He has averaged four films a year over the last 20 years, making six in 2010, four in 2011 and signing up for three next year (2012).
