Two years ago, on the set of Hollywood picture Ocean’s Eleven, Lewis filmed a fight scene with the younger Klitschko, Vladimir, while elder brother Vitali watched from ringside.
Now Lewis will step inside the ropes to face Vitali, with his WBC heavyweight title at stake.
The 37-year-old Briton’s manager, Adrian Ogun, said on Friday that the fight would definitely take place, probably at the end of February or the beginning of March in the United States.
It was during the film, about a daring plan to rob three Las Vegas casinos during a fight night, that Lewis told the brothers he could have one for breakfast and the other for lunch.
Now he might have to eat his words.
Boxing insiders knew Vladimir for having won the Olympic super-heavyweight title in 1996 in Atlanta but Vitali was by no means a star.
Since joining Kohl’s Universum stable, the brothers, who train in Hamburg, have been promoted as a package and are now among the country’s most popular sports celebrities.
Vitali, 31, is a dangerous puncher and a formidable athlete but has yet to be tested against a big name fighter.
