Thanks to James and Sharkington for the info.
I wonder if the real name is being kept secret to hide a bigger identity? Could he be playing a young Marvin Candle in a flashback or his son? How about a Mr Paik associate?
Ken Leung – whose memorable turn as Uncle Junior's mentally unstable protégé on The Sopranos last season turned many a head in Hollywood (mine included) – is joining the cast of Lost next season, sources confirm to me exclusively.
It's believed Leung will be playing the recurring role of Russell*, a brilliant mathematician who is capable of great insights and has a tremendous knowledge across various scientific fields. He's expected to first turn up in February's season premiere.
Non-Sopranos fans may know Leung from his role as Kid Omega in Brett Ratner's franchise killer, X-Men: The Last Stand.
* May not be the character's real name.
