(RENT)said yesterday in an e-mailed statement. “Teenage Mutant Ninja Turtles,” fromViacom Inc. (VIAB)’sParamount Pictures, placed second with $6.5 million in its fifth week. Ticket sales for all movies were $65 million, the weakest total since the weekend that started Sept. 21, 2001,Paul Dergarabedian, senior media analyst at Rentrak, said by telephone yesterday. Sales followed the typical slowdown that occurs after the U.S. Labor Day holiday, he said. Also, there were no new breakout releases. “The sky is not falling,” Dergarabedian said. “Summer was down almost 15 percent, so it’s not so surprising that the transition to fall is a little slow.” “Guardians of the Galaxy” is the top-grossing film of the year, with $294.6 million in domestic ticket sales. With two other films in 2014’s top five -- “Captain America: Winter Soldier” and “Maleficent,” -- Disney ranks second among studios to 21st Century Fox Inc., and is up 6.2 percent for the year, according to Box Office Mojo.Photographer: Kevin Winter/Getty Images for Paramount Pictures Actress Megan Fox attends the premiere of "Teenage Mutant Ninja Turtles" at the Regency...Read MoreLess Competition “‘Guardians’ is benefiting huge from its late-summer release date,” Dergarabedian said. “The movie was positioned perfectly to take advantage of the much less crowded and competitive time frame and the results speaks for themselves.” “Captain America” and “The Lego Movie” each led the domestic box office three weekends this year, Dergarabedian said.
