*Tyler Perry’s “For Colored Girls” earned a Lionsgate-estimated $20.1 million in its opening weekend to place third at the box office.

The DreamWorks Animation’s 3-D comedy “Megamind” won the weekend with a studio-estimated $47.7 million, while “Due Date,” a reunion between “The Hangover” director Todd Phillips and star Zach Galifianakis, took 2nd place with $33.5 million, according to Warner Bros.

The $20.1-million opening for “For Colored Girls,” Perry’s adaptation of Ntozake Shange’s stage play, was slightly below industry forecasts that had it closer to $25 million, according to the Los Angeles Times.

The movie’s tally is lower than his previous three openings — including his record-best $41 million for “Madea Goes to Jail” and last year’s $29 million for “Why Did I Get Married Too?”  But it was also higher than his lowest-performing comedy, the $17.3 million opening for “The Family That Preys.”

The LA Times blog Company Business notes…

“Colored Girls” will be an unassailable financial triumph for Lionsgate, which spent only about $21 million to produce the film. And the drama could enjoy strong word of mouth and a long run at the box office — the movie garnered an ‘A’ Cinema Score and could generate awards talk for its ensemble of A-listers that includes Whoopi Goldberg and Janet Jackson. It also will be helped by an older fan base — 87% of the audience this weekend was over the age of 25 — which tends to wait until the second and third weekends to see new movies.
