Land of the Lost (2009, dir. Brad Silberling)

A debunked anthropologist and his companions are accidentally transported to an alien world. A deliberately daft semi-spoof version of the 70s TV show, focusing on set-piece comedy, improvised moments and on some rude running gags. Not bad if you go with it, though not for everyone, the flick relying on your capacity for its star’s mugging.

Holmes & Watson (2018, dir. Etan Cohen)

A celebrated detective battles a plot to assassinate Queen Victoria. A great cast, handsome production values and enthusiastic playing can’t save this mess, seemingly compiled from extensive on-set improvisations rather than a script. Inevitably, some fine moments, but this is a skit stretched to 90 minutes.

Elf (2003, dir. Jon Favreau)

One of Santas’s elves discovers he’s human; he journeys to New York to find his father. Generally solid Christmas comedy which keeps its single joke going for a good hour before a plot is hastily bundled in (the usual “save Christmas” one).
