The actress was at the house where she is staying while making the sci-fi movie when she mis-stepped, causing her injury.
Sources told website TMZ she was taken to hospital where he foot was put in a cast. She later left the medical facility in a wheelchair.
The film`s directors, Tom Tykwer, Andy Wachowski and Lana Wachowski, are overcoming the immediate problem of shooting Halle`s scenes - in which she plays one of few remaining survivors in a post apocalyptic world - by filming her from the waist up, using a stunt double, or simply shooting other scenes in which she is not required.
Speaking of the film, Tom has promised it will be of an epic proportion, saying: "The big-scale adult movie is a dying species. Where are the `2001s` and the `Lawrence of Arabias`?
"You go to all these studios, and you see their framed photographs, the films they`re so proud of, and you wonder: `Where are the pictures this year that they want blown up with a nice expensive frame around it?`"
Other A-list stars to appear in the big budget adaptation of the novel by David Mitchell include Tom Hanks, Hugh Grant, Jim Sturgess and Hugo Weaving.
Halle is not the only star to have been hurt in an accident in recent weeks. `True Blood` actress Evan Rachel Wood lost a tooth after being hit in the face by an erratic dancer at a Parisian nightclub, where she was celebrating her 24th birthday earlier this month.
