Jeff Goldblum has joined the cast of The Liar, based on the book by Stephen Fry.

He joins Asa Butterfield who will play the lead character Adrian Healey who may or may not have been recruited as a spy by a mysterious Cambridge professor – played by Goldblum.

“I hiccupped with delight when I heard that Jeff Goldblum had accepted the role of Donald Trefusis,” Stephen Fry told Deadline. “That uniquely perfect mixture of authority, eccentricity, intelligence, humour and charm is just what the character calls for…hurrah.”

Filming on the project begins next month.
