Following Andy Murray's win at the Aegon Championships at Queen's Club, London, the British star took part in a special Rally Against Cancer match.
The game was organised to raise money for The Royal Marsden Hospital, in support of Murray's best friend and fellow player Ross Hutchins, who was diagnosed with Hodgkins lymphoma in December.
Tim Henman returned to Queen's to partner Murray in a doubles match against world number six Tomas Berdych and multiple Grand Slam champion Ivan Lendl, Murray's current coach.
After the humorous match, which included Murray succeeding in his attempt to smack a ball at his coach, several celebrities took to the court to partner Henman and Murray.
Sir Richard Branson, Jimmy Carr, Jonathan Ross and Les Misérables actor Eddie Redmayne completed the lineup of stars.
Johnson showed off his tennis skills with a 19th century wooden racket, while McIntyre also pulled off a number of impressive shots.
At one stage, Branson managed to bribe the umpire into giving his team a point after upgrading his Virgin flight seats.
Rally Against Cancer managed to pass its fundraising goal by 49%, reaching £149,680 through its Just Giving page.
