Marsan will portray Inspector Lestrade, a Scotland Yard detective and ally of Holmes in Guy Ritchie's revamped story of the Baker Street sleuth.
The actor, whose credits also include Happy-Go-Lucky, Miami Vice and Mission: Impossible III, said: "I'm doing Sherlock Holmes with Robert Downey Jr. I play Inspector Lestrade. Holmes describes him as a man with no imagination."
Speaking to DS about how the movie will differ from previous incarnations, Marsan added: "Holmes and Watson are a lot younger, bohemian. It works. Reading the script, Robert Downey Jr. is just perfect for a modern-day Holmes. Also he's a bit of totty, as well!"
Jude Law, Mark Strong and Rachel McAdams are already among the Sherlock Holmes cast.
Marsan can next be seen as Mr. Pancks in the Charles Dickens adaptation Little Dorrit, which airs this autumn on BBC One.
