Will Arnett is known for his signature gravelly voice, which made him the perfect actor to voice the title character in “The Lego Batman Movie.”
Appearing on BBC Radio 1’s “The Matt Edmondson Show,” Arnett put his Batman voice to use beyond the animated film world. Edmondson prompted the actor to make a prank call to a local toy store and speak to employees using his character’s voice.
Another hitch: He had to start each sentence with a different letter of the alphabet in order.
Watch Arnett’s hilarious (and impressive) prank call mission in the video above.
