The Cartoon Characters You Never Realized Were Voiced By Jason Isaacs

Having been in the industry for over two decades, Jason Isaacs has nearly 150 acting credits to his name (via IMDb). From starring in blockbusters like "Fury" and "Black Hawk Down" (via Screen Rant) to portraying iconic characters such as Lucius Malfoy in the "Harry Potter" franchise, Isaacs has become very familiar with thousands of movie goers.

However, you may not have realized that Isaacs has quite the established career in voice work. Both in television and video games, Isaacs has somewhat disguised his voice to a point where you only just realize its him. For example, you may never had known that Lucius Malfoy wasn't the only major role Isaacs has had in the series. He also voiced the main antagonist of "Harry Potter and the Chamber of Secrets" –- the Basilisk (via YouTube).

But what other animated characters has Jason Isaacs voiced? He's collected quite the filmography since his first voice role in 1991.

In 1994, Isaacs was involved in his first video game role as Ken in "Beneath a Steel Sky," albeit in an uncredited capacity (via IMDb).
