Actor Morgan Freeman attends the world premiere of The Dark Knight Rises in New York.

Los Angeles - The Warner Bros film studio on Monday said its new movie The Dark Knight Rises took in $160.8-million at US and Canadian box offices over the weekend, which is at the lower end of industry estimates for the debut that was marred by a shooting incident at a Colorado movie theatre.

Warner Bros, a unit of Time Warner, had no initial comment beyond simply releasing the ticket sales total.

The Dark Knight Rises, which in advance of its release was forecast by some box office watchers to bring in anywhere from $170-million to $198-million, saw its debut marred by a tragic shooting at a midnight screening of the film in a Denver, Colorado suburb that left 12 people dead and 58 injured.

The movie is expected to be among Hollywood's biggest blockbusters of the year. - Reuters
