The pair denies the allegations, saying that the tiger was trying to help Roy after he suffered a stroke. The special features interviews with Curtis Rowe, the stagehand who helped save Roy’s life by plugging wounds with his fingers; longtime producer Kenneth Feld; and Las Vegas magicians Criss Angel, Lance Burton and Penn & Teller.

If you’re not already listening to the corresponding “Dateline” podcast, “The Thing About Pam,” check it out.
