The contents of a suitcase recently retrieved from a bank vault will feature in a new BBC Two documentary about football legend George Best.

Marking a decade since the former Manchester United footballer’s untimely death, Best will include a “stellar” cast of interviewees as well as previously unseen footage.

Announcing the commission, the BBC intriguingly reveals that the 60-minute film, produced by Finepoint Films, will feature the contents of a suitcase.

The broadcaster said: “In the depths of his spectacular fall from grace, George Best deposited a suitcase in a secure vault of his bank. It lay there, forgotten, for many years after his death.

“The opening of that case and the revealing of its contents will bookend a film that brings fresh and compelling insight to the story of a very familiar figure.”

Directed by Sheffield filmmaker Dan Gordon and executive produced by John Battsek – who also collaborated together on the award-winning Hillsborough – Best will aim to “unpack the highs and lows of George Best’s life on and off the pitch to make sense of a very public implosion”.

The new documentary was one of a series announced by Kim Shillinglaw, controller of BBC Two and Four.
