Eriq Lasalle is set to join the cast of “Wolverine 3” starring Hugh Jackman.

Boyd Holbrook and Stephen Merchant are also on board. James Mangold is directing.

Plot details are being kept under wraps, as are details behind Lasalle’s role. David James Kelly penned the script.

Fox has scheduled “Wolverine 3” for March 3. “X-Men Origins: Wolverine,” directed by Gavin Hood, was the fourth film in the X-Men series and grossed $375 million worldwide in 2009. Four years later, Mangold directed “The Wolverine,” which grossed $415 million worldwide.

“The Wolverine” was the sixth film in the X-Men universe, followed by “X-Men: Days of Future Past,” “Deadpool” and “X-Men: Apocalypse,” which opens May 27. “Wolverine 3” will be the 10th film in the franchise.

Best known for his portrayal of Dr. Peter Benton on NBC’s smash medical drama “ER,” Lasalle most recently recurred on CBS’ “A Gifted Man” and “The Widow Man.”

Lasalle has also been directing episodes of TV shows such as “CSI: Cyber,” “Madame Secretary,” “Crisis,” “Battle Creek” and “Night Shift.”

He is repped by Principato-Young Entertainment, Paradigm and attorney Fred Toczek.
