We recently shared a video of an announcer who drops 13 Breaking Bad references during a Serena Williams match, but now we've learned that Walter White prefers baseball from a tweet from one of the show's writers/producers.
Apparently, in addition to being a chemistry teacher-turned-drug tycoon, Heisenberg is also a fan of Philadelphia baseball, based on a shot from this unused scene from the third season.
An explanation in a following tweet revealed that Bryan Cranston, who plays White on the show, is actually a Phillies fan.
@briangoff Bryan was goofing around on set of #307 "One Minute" -- he actually is a Phillies fan!— Thomas Schnauz (@TomSchnauz) October 10, 2013
Thanks to Sporting News MLB for the find.
