Colin Farrell has been added to that cast of the upcoming film Saving Mr. Banks, which charts the story of PL Travers, who sold Disney the rights to her work Mary Poppins.

The actor will appear alongside Tom Hanks (Walt Disney) and Emma Thompson (PL Travers).

The Hollywood Reporter is due to start production this fall. Farrell is set to play Traver’s father, who was the inspiration for the character of George Banks. The film will shift back and forth between 1961 and 1907. The film will cover Travers childhood, as well as her negotiations with Disney execs.

The film will focus on the tense relationship between Disney and Travers, who was reluctant to sign over her material to the studio head. Travers hated the animated sequences so much that she refused to sell any more of her work to Disney or anybody else.

Farrell’s latest movie, the Total Recall reboot is set to premiere August 3.
