The 78-year-old "Silence of the Lambs" star has signed on to play a major character in "Transformers: The Last Knight."
Hopkins will join Mark Wahlberg, Isabela Moner, Jerrod Carmichael, and Josh Duhamel in the sequel, reported Ace Showbiz.
Announcing the casting news, a post on director Michael Bay's official Twitter account read: "The man, the myth, the legend - help us welcome Sir Anthony Hopkins to the #transformers universe."
The casting news comes hours after Bay announced Freya, an epileptic six-year-old Staffordshire bull terrier that was last month dubbed Britain's loneliest dog, will also appear in the fifth "Transformers" movie when it hits theatres in June, 2017.
