Disney changes its ‘Game Plan’

Disney has postponed production of a film called “The Game Plan” after star Dwayne Johnson, better known as the Rock, ruptured his Achilles tendon Monday while preparing for his role as a professional quarterback.

Johnson will undergo surgery in Miami on Friday, a studio spokesman said Tuesday.

The movie, described as a family comedy in which Johnson’s character discovers while preparing for a championship game that he has a young daughter, was to have begun filming in Boston next week.

It will be on hiatus until Johnson is fully recovered, the spokesman said.
