“Calvin and Hobbes” fans, rejoice: a biopic about comic strip creator Bill Watterson is in the works, and Leonardo DiCaprio is set to help produce.

Warner Brothers has acquired the film, written by Dan Dollar.

“A Boy and His Tiger” will chronicle the “Calvin and Hobbes” creator’s early life and will relate how the notoriously media-shy artist dealt with the sudden fame he experienced as a result of the strip’s popularity, Tracking Board reports.

Watterson, who was famous for not licensing his characters like Charles Schultz and Jim Davis did with “Peanuts” and “Garfield,” respectively, has declined interviews and speaking engagements for years.

A recent 2013 documentary, “Dear Mr. Watterson,” examined the cult following devoted to “Calvin and Hobbes,” but little is known about the man who made the iconic comic strip.

No casting decisions have been reported at this time.
