Film fans gambled on Kevin Spacey and Kate Bosworth for a second week, giving the couple's Las Vegas film 21 the edge over George Clooney's sports comedy Leatherheads at the box office.

The gambling film took in just over $15 million at the box office during its second weekend on release to extend its stay at the top of the box office to two weeks.

"Leatherheads" opened in second place with a disappointing $13.4 million, just ahead of Jodie Foster's new family film Nim's Island, which has debuted at three on the new chart.

Rounding out the top five is Jim Carrey's animated comedy Dr. Seuss' Horton Hears a Who! and horror film The Ruins, which is the only other new entry in this weekend's top 10.
