I thought for years that this was a typical bottle of J&B and had been putting off posting the clip for quite some time. Upon closer examination it appears that this is actually a fake label which reads "L&D". Not sure if those letters have any significance. Guy Pierce's character is named Lenny but perhaps I'm reading too much into this.
Here's a couple of other sightings from Christopher Nolan films:
Highland Park and Black Grouse Spotted in "Inception"
Clyburn Sighting From "The Dark Knight"
