Peter Dinklage (TV's "Threshold", "Find Me Guilty") is the first to come aboard "Underdog," Walt Disney Pictures and Spyglass Entertainment's live-action big-screen adaptation of the classic 1960s cartoon says The Hollywood Reporter.
"Underdog" followed the adventures of a humble dog named Shoeshine Boy who became the superheroic Underdog who spoke in rhymes.
Dinklage will portray Simon Barsinister, an evil scientist who once created a Big Dipper Machine in an effort to steal the world's water supply. Shooting begins April 10 in Rhode Island under the helm of Frederik Du Chau.
