Stéphane Ronchewski is a French actor and writer, born on November 21, 1968. Specializing in voice acting, he is best known for voicing Michael Richard Kyle (played by Damon Wayans) in the TV series My Wife and Kids, as well as the Joker (played by Heath Ledger) in The Dark Knight and several Batman video games. He is also the regular French voice of David Tennant and one of the dubbing voices of Adrien Brody.

In 1997, he began working in dubbing and was immediately drawn to the calm, intimate atmosphere of the studios. Today, he lends his voice to American, British, German, and Italian actors, and frequently helps bring animated characters to life. His work also includes narrating documentaries and novels, performing voice-overs, commercials, and video games — which form the core of his professional activity.
