The holidays are about to get witchy.
San Giacomo will play "La Befana—a Christmas Witch from Italian folklore who delivered treats to good children on the morning of the epiphany," according to the outlet. "She now resides in the Wobbly Woods of the North Pole."
The Santa Clauses is a series revival of 1994's The Santa Clause and its sequels, which starred Tim Allen as Santa (a.k.a. Scott Calvin).
Allen reprises his role in the series, in which "Scott is on the brink of his 65th birthday and realizing that he can't be Santa forever," according to Disney+. "He's suddenly starting to lose his Santa magic, and more importantly, he's got a family who could benefit from a life in the normal world, especially his two kids who have grown up at the North Pole."
The Santa Clauses also stars Kal Penn, Rupali Redd, Devin Bright, Matilda Lawler and, in a bit of holiday magic, Allen's own daughter Elizabeth Allen-Dick, making her acting debut.
In addition to her role as magazine writer Maya Gallo on Just Shoot Me!, San Giacomo's other television credits include Saving Grace, NCIS and, most recently, a memorable turn on the third season of Barry.
She also won an Independent Spirit Award for her role in 1989's Sex, Lies, and Videotape.
The Santa Clauses will premiere later this year on Disney+.
