💥 Run Fatboy Run Reviews
Personal Review
I went into this movie expecting a silly, over-the-top comedy, and that’s pretty much what I got! Simon Pegg is fantastic as the lovable loser, and I found myself genuinely rooting for him. The training montages were hilarious, especially the scenes with his unconventional landlord. While the ending was predictable, it still left me with a warm, fuzzy feeling. It’s not a masterpiece, but it’s a fun, feel-good movie perfect for a lazy evening. I especially loved Dylan Moran as the gambling best friend!

Awards
🛠️ Behind the Scenes

Normally, actors use a nude pouch for nude scenes, but the pouch wouldn’t stay put on Hank Azaria, who ultimately decided to forgo wearing it. Simon Pegg’s shocked reaction when Hank Azaria drops his towel is genuine.”
- “David Walliams of Little Britain makes a cameo appearance in the bakery.”
- “The closing credits are shown in hard-to-read footprints, mimicking a marathon runner’s path.”
