HOLLYWOOD — Turns out New Line’s “Secondhand Lions” was second in line at the box office this weekend, as Monday’s official tallies reversed the No. 2 and 3 positions on the frame. New Line distribution prexy David Tuckerman welcomed the validation of a silver-medal finish for “Lions,” a performance-driven family pic toplined by Michael Caine, Robert Duvall and Haley Joel Osment. “We were very careful in picking this date,” Tuckerman said. “We are probably supporting this picture more in its second week than we have with the majority of our films, because we feel it’s going to have legs.” Helping in that cause will be distrib’s attaching a trailer for the final “Lord of the Rings” movie, “The Return of the King,” which is set for release Dec. 17.
