Both are by non-professionals
The first is Terry Frost's Paleo Cinema, a fairly regular podcast on movies pre-dating 1980. Terry's range of tastes and knowledge is fairly eclectic and encyclopedic, though as he is the first to admit, he's no expert. Terry forewent a formal study of cinema, and instead simply grew up watching lots of films.
His shows are usually well put together and presented, and it tends to feel like you're sitting around chatting with him, rather than being talked at. I don't always agree with his views and criticisms, but there hasn't been a single show I haven't enjoyed.
I checked out a couple of random podcasts, but have now gone back to the start and am running through the shows in order. Highly recommend it.
The other is The Bazura Project, a movie show that screens on Channel 31. Shannon Marinko and Lee Zachariah present a half-hour program of news, reviews, interviews, entertainment and general silliness. Every show opens with a short parody of a well-known film (there's only been one I haven't picked so far).
My attention was first drawn to the Bazura Project by this report on Media Watch about their efforts to get nominated for a Logie.
All three seasons are watchable on their website, and on youtube. I started from the first episode and I'm now nearing the end of season two.
What I enjoy about both shows are that they are simply people who love movies talking to you about them. It's rare I come away from either without wanting to check out something new, or rewatch something old.
