July 23 (UPI) -- Penelope Ann Miller has joined the cast of The CW's young-adult drama Riverdale for Season 3.
The show is a pitch-dark Archie Comics adaptation.
Miller, whose credits include The Artist, Carlito's Way and The Freshman, will play Ms. Wright, a prosecutor determined to convict Archie Andrews (played by K.J. Apa) of a murder Hiram Lodge (played by Mark Consuelos) framed him for at the end of Season 2, The Hollywood Reporter said.
Season 3 of Riverdale is to begin Oct. 10. A 3-minute trailer previewing what fans can expect in the upcoming episodes was shown during the weekend at San Diego Comic-Con.
Showrunner Roberto Aguirre-Sacasa also told the crowd during a panel discussion about the series, "There will definitely be another musical episode," according to EW.com.
