With films aimed at mature audiences gaining in popularity, 'My Old Lady' seems like a sure-fire formula for a hit. It stars the grand dame of theatre and cinema, Maggie Smith, in a lively role that makes the most of her expertise at delivering a withering look, honed to perfection over five series of 'Downton Abbey'.

Meanwhile, 'My Old Lady' also offers a plum role to Oscar-winner Kevin Kline, as a cantankerous guy struggling to get his head around the fact that the palatial Parisian flat he has just inherited comes complete with an octogenarian resident. Kline hasn't had a role quite this juicy since he played Cole Porter in 'De-Lovely' 10 years ago.

And here he also stars opposite Kristin Scott Thomas, another performer who is beloved by older film fans. Scott Thomas has varied her career with big blockbusters ('Mission: Impossible'), ensemble romps ('Gosford Park'), prestige movies ('The English Patient'), maverick classics ('Only God Forgives') and lots of small French dramas shot around Paris, where she lives.
