LOS ANGELES, March 31 (UPI) -- "G.I. Joe: Retaliation" was the No. 1 movie at the U.S. box office, grossing an estimated $41.2 million in its opening weekend.
The figure fell considerably short of matching the opening weekend take of "G.I. Joe: The Rise of Cobra" -- $54.7 million in 2009 -- Box Office Mojo said.
