Several movies that warm up the already simmering winter film season will open in the area this weekend. “Pirate Radio,” which plays at Bangor Mall Cinema and at Railroad Square Cinema in Waterville, tells the true story of a pirate radio station in England in the 1960’s, who boarded a boat in order to escape censorship of the music they broadcast to the masses. Phillip Seymour Hoffman and Bill Nighy star in this acclaimed comedy. Also premiering this week is “Paris,” a loving tribute to the City of Lights, starring a veritable who’s-who of French cinema, including Juliette Binoche and Melanie Laurent, recently seen in “Inglourious Basterds.” Finally, Railroad Square Cinema continues to screen “A Serious Man,” the new movie from the Oscar-winning Coen Brothers. It details the unraveling of the life of a 1960s college professor, in the Coens’ trademark darkly humorous style.
