On publication in 2003, Audrey Niffenegger’s fantasy romance became a US bestselling smash and global book-club swoon. Travelling forward in time to 2009, it now becomes an outrageously daft, but occasionally entertaining Hollywood movie. Eric Bana plays Henry, an unshaven and agonised-looking guy who works in a Chicago library. Henry has a strange disorder, which means that he will unpredictably succumb to a epileptic-type fit ­during which he will vanish, and then travel backwards or forwards in time or space, usually only for a few hours. It is very silly and of course cannot submit to close inspection. Distracting you from these nagging pedantries is a startlingly farcical plot with some bizarre touches. In the end, the tasty nuggets of fun drown in all the soupy seriousness.
