Bob Geldof‘s battle to stage Live Aid after being inspired by the Ethiopian famine is to be turned into a TV film.

When Harvey Met Bob is being billed as a “hilarious and deeply moving” drama about the Irish singer’s collaboration with promoter Harvey Goldsmith to stage the global concert.

Monday marked the 25th anniversary of the event, staged mainly in London and Philadelphia, which saw many of the world’s biggest music stars performing.

Domhnall Gleeson – Bill Weasley in the final Harry Potter films – will play the former Boomtown Rats star while Ian Hart will play promoter Harvey.

Filming has already begun in Dublin and When Harvey Met Bob will be screened on BBC Two later this year.

It will follow Bob from the moment he arrives home in 1984 to find his then girlfriend, and later wife, Paula Yates watching Michael Buerk’s BBC broadcast from the camps in Eritrea.

Moved by what he saw, he first sprang into action by organising the Band Aid single Do They Know It’s Christmas? and then the following year staged the massive Live Aid gig.

Janice Hadlow, controller of BBC Two, said: “To mark the 25th anniversary of Live Aid, BBC Two celebrates with an ambitious single drama which tells the story behind the biggest televised international charity event in history and the two inspiring men that made it happen.”

Executive producer Kate Triggs of Great Meadow Productions said: “We were inspired by this story because it has, at its heart, a fantastic relationship that is funny and moving and born out of the real drama of trying to achieve something huge and unprecedented.”
