If you've been keeping up with the final season of Breaking Bad then you'll be aware that the already dark tone is getting increasingly darker by the episode.
But despite his ruthless on-screen persona, Bryan Cranston was keen to keep things light for co-star Aaron Paul.
In this week's ShortList, we found out that their final scene together features a rather surprising cameo...
"I remember the final scene that he and I were shooting together," Paul reminisced. "It was this serious moment, I’m talking to him and I hear everyone laughing outside of the set and I’m like, “Why is everyone laughing?” Then I realise. He turns away from me and starts walking and I can see that his ass is out. Right in front of the camera."
