How soon do you want it to get moving? I'm not the most encyclopedic person here but I have a fairly advanced working knowledge of the films, BTS and EU, - enough that with a bit of homework for each session I could get by happily, have some experience being a frontman (although it was a band, not a podcast), and I'm told that kiwi accents are good and neutral for international affairs like this.
However, I'd need a month or two to get set up with a decent mic and associated tech, so if you get someone equal or better, sooner, go ahead.
