Actor Bryan Cranston helped a fan ask a girl to the prom by recording a video message for him.

The Breaking Bad star was approached by Stefan Montana outside his Broadway show All The Way on Thursday (10Apr14) and the teenager asked if the actor could help him secure a prom date with a girl named Maddie.

Cranston recorded a video message, saying, "Maddie, if you don't go to prom with Stefan, then maybe your best course of action would be to tread lightly," a reference to a line from the hit drama, which Cranston delivered in the menacing voice of his character Walter White.

The high school student posted the video on his Instagram.com page and Maddie accepted his invitation.
