Deadline reports that Ernie Hudson will guest star in episode 15 of Once Upon A Time.
The former Ghostbuster will play Poseidon, who is know to be the father of Ariel (i.e. “The Little Mermaid”), with JoAnna Garcia Swisher (Reba) reprising her guest role, but apparently we will find out that he is also the father of Ursula, played by Merrin Dungey (Alias), who made a couple appearances so far this season including the mid-season finale.
The second half of the current season appears to be leaving their Frozen mini-sequel behind for a more up front battle with Disney villains, with Rumpelstiltskin/Mr. Gold joining Ursula, Cruella DeVil (Victoria Smurfit) and Maleficent (Kristin Bauer van Straten) in an attempt to find “The Author” and change their story.
