Inception made it three weekends in a row at the top thanks to an estimated $27.5m haul that raised Warner Bros and legendary Pictures’ sci-fi thriller to $193.3m.

DreamWorks’ French comedy remake Dinner For Schmucks directed by Jay Roach and starring Steve Carell and Paul Rudd opened well in second place on $23.3m, while Sony’s spy thriller Salt fell one place to third on $19.3m for $70.8m after two weekends.

Warner Bros’ family sequel Cats & Dogs: The Revenge Of Kitty Galore voiced by Christina Applegate, Neil Patrick Harris and James Marsden, among others, scored a disappointing $12.5m in fifth place. Universal’s animation DespicableMe in fourth place is a cast-iron smash for the studio and has reached $190.3m after four weekends.

However Charlie St Cloud, the Zac Efron melodrama co-financed with Relativity Media, struggled to break into the top pack and launched in sixth place on a lacklustre $12.1m. Disney’s Toy Story 3 in seventh has amassed $389.7m after seven weekends in release.

Sony’s strong summer continued as the comedy Grown Ups in eighth place added $4.5m for $150.7m after six weekends. Summit’s The Twilight Saga: Eclipse ranks tenth and stands at $288.2m after five.

Next weekend’s wide releases are Sony’s comedy The Other Guys with Will Ferrell, Mark Wahlberg and Eva Mendes, and Buena Vista’s Step Up 3-D.
