It appears the film will be dishing some back story on both Ms. Rainier and Lorraine Lambert, Barbara Hershey’s character.
Last month, it was revealed Jocelin Donahue was brought aboard to play “young Lorraine Lambert.”
Seim joins Patrick Wilson, Rose Byrne and Ty Simpkins in the film – all of whom are reprising their roles in the James Wan-directed film.
Insidious Chapter 2 opens September 20th.
