Marvel's 'Moon Knight' featuring Oscar Isaac debuts on March 30

Hollywood star Oscar Isaac portrays    a lesser-known Marvel hero in the  new Disney+ show "Moon Knight".

"That was part of the challenge and the excitement of taking this on, the opportunity to show so many facets of one individual and really explore in a literal and symbolic way the different identities that he has," Isaac told Reuters as he premiered the series at the British Museum on Thursday.

In a twist from the comic books, in which Moon Knight's alter ego is the Jewish-American mercenary Marc Spector, Isaac plays gift shop worker Steven Grant. The sleep-deprived Londoner suffers from dissociative identity disorder and is haunted by memories of Spector.

"The emotional reality of struggling with this disorder and not only that, but the journey of healing from abuse and trauma, that really became the central orienting theme of the whole thing. Everything you see, including the really crazy symbolic imagery, is an expression of that internal struggle," Isaac said.

The series, directed by Egyptian filmmaker Mohamed Diab, also features French actor Gaspard Ulliel, who died after a ski accident in the French Alps on Jan. 19, in his final completed role.

"Moon Knight" debuts on Disney+ on March 30.
