Eccentric moviemaker Terry Gilliam is planning to revive his 'disaster' movie about Spanish literary legend Don Quixote.

In Brothers of the Head (Tartan, €24.99) the mockumentary approach works well in telling the fascinating story of conjoined twins Tom and Barry Howe (Harry and Luke Treadway) who ended up fronting glam-punk band Bang Bang in the ’70s.

Joined twins Barry and Tom – the Treadaways – are lifted from obscurity to become a headline-grabbing rock band, and the subject of a documentary film … in a film that is in itself a mock doc.
