Joe Exotic's husband Dillon Passage has let slip that filming is already underway on the second season of Tiger King.

Earlier this month it was reported that Netflix was keen for more episodes of the bizarre documentary series, which became a worldwide hit during the early weeks of the coronavirus lockdown.

Exotic is now imprisoned and his rival Carole Baskin has furiously ruled out reappearing on the show, with the second season likely to comprise previously-unseen footage and fresh interviews with the participants.

"I've done a little bit of filming for [season two]," Passage told Good Morning Britain. "I do not know the release date but It's going to be very interesting because it will tell a little bit of Joe's arrest and afterwards.

"I know there's going to be some phone call recordings of Joe that is going to be in it. There is no filming since he's incarcerated."

Exotic and his legal team are in the process of petitioning US President Donald Trump to grant him a pardon in order to secure his release.
