The film will focus on the German sports star's childhood and the road to his record-breaking triumph at the Wimbledon final in 1985.

Becker became the first unseeded player to win the tournament and the youngest ever men's singles victor at the age of 17, a record he still holds.

He tells the BBC, "There's a right time for everything in life... Now, on the 30th anniversary of my first big win, it seems the time has come to tell the story in a movie."

Becker retired from professional tennis in 1999 and currently coaches world number one Novak Djokovic.
