The TV equivalent of raiding a bare cupboard, the supposed extra hour here is cobbled together from previous DVD extras – but you can’t miss the tension between Harrison and McCartney

There’s no doubt that the arrival of The Beatles Anthology in 1995 was a big deal. The TV series was broadcast at prime time on both sides of the Atlantic, and ABC in the US even changed its name to ABeatlesC in its honour. The three accompanying albums (the first time the Beatles had allowed outtakes from their recording sessions to be officially released) sold in their millions. Its success helped kickstart the latterday Beatles industry, a steady stream of officially sanctioned documentaries, reissues, remixes, compilations and expanded editions, predicated on two ideas: that the Beatles’ archive contains fathomless bounty; and that the band’s story is so rich there’s no limit to the number of times it can fruitfully be retold in fresh light.

For a while, those ideas seemed to hold true, but recently, it’s been hard not to think the Beatles’ Apple Corps might be trying to feed an insatiable appetite for content from an increasingly bare cupboard. You can marvel at the highlights of Peter Jackson’s TV series Get Back and still wonder whether the director wasn’t stretching his material a little thin; whether nearly eight hours of it – plus a separate Imax film of the Beatles’ final live performance on the roof of Apple’s London HQ, and a reissue of the original 1970 Let It Be documentary – might have been rather too much of a good thing.
