BBC Four has a new series for film buffs at 9pm: Mark Kermode's Secrets of Cinema. The film critic examines the tricks and techniques behind popular movie genres. Tonight he looks at romantic comedies, from Bringing Up Baby to La La Land.

Tonight’s best film recommendation is David Fincher’s The Girl with the Dragon Tattoo (2011), at 9pm on Sony Movie Channel. A journalist (Daniel Craig) recruits the help of a reclusive computer hacker (Rooney Mara) to solve the case of a teenager who disappeared 40 years ago. The English-language remake, based on Stieg Larsson’s book, “is sleeker, smoother, sexier than its Swedish predecessors”, says The Guardian.
