Who says the Golden Globes don’t matter? Jumping off a big win at the kudofest Monday and helped by an otherwise weak field, “Brokeback Mountain” garnered the impressive achievement of a solid No. 1 win at the box office Tuesday and Wednesday despite playing just 682 theaters. That puts “Brokeback” in a very strong position as it expands this weekend to 1,194 playdates — a significant boost from the 800-900 Focus was planning before the Globes victories. Also bowing, and considered a lock for the top weekend spot, is Sony Screen Gems’ “Underworld: Evolution.” Indie distrib Rocky Mountain Films will be aiming for the Christian aud with “End of the Spear,” while New Line puts Terence Malick’s “The New World” in a small wide run and Warner Independent debuts Albert Brooks’ comedy “Looking for Comedy in the Muslim World” in limited release.
