What listeners say

A curated, balanced selection of Apple Podcasts reviews.

Very much a fan of Firefly, but the podcast has a lot more to offer. As someone who has considered getting involved in the business in some way, there are a lot of tidbits of wisdom in here, as well as a ton of general humor, etc. I look forward to the episodes each week. Thank you and keep them coming.

Medery · Aug 2026

What do you get when two of the funniest and charming people get together to do a podcast? You get a hilarious and insightful time, of course! The interviews are fun and relaxed and you also get some TMI you’ll never forget :P I look forward to this one every week!

Tzorko · Aug 2026

I even listen to the outgoing credits cause the hilarity and fun don't stop at the end of the show! Some good guests but my favorite episodes are when Alan and Nathan are just BSing and sharing things about themselves and their lives. My go-to podcast when I just want something fun and interesting without any crapola ;)

CanadaAngel71 · Jul 2026

This is a great podcast. I have been a fan of these guys for years. It’s great getting to hear more about their lives, learning more about Hollywood magic 🪄. If you’re a fan of Firefly, Castle, the Rookie, or even a fan of Alan’s voice, this is the podcast for you.
