The 29-year-old actor is reprising his role as fading television star Valerie Cherish's (Lisa Kudrow) 'Room and Bored' co-star Chris MacNess, reported Deadline.
Lutz will appear in multiple instalments of 'The Comeback's six-episode second season.
Chris's storyline will reportedly see him romantically involved with fellow 'Room and Bored' star Juna Millken (Malin Akerman).
The first teaser for 'The Comeback's return premiered in May, two weeks after HBO announced that it will air the new episodes in the fall.
'The Comeback' originally aired for a single season back in 2005.
