New powerhouse trailer for Johnny Depp's Black Mass

Remind us never to ask Johnny Depp for parental advice.

After an equally tense dinner conversation in the first trailer for Black Mass, Johnny Depp's balding baddie is at it again with the unwanted table talk, imparting some overly serious advice to a six-year-old.

Depp plays as real-life Boston crime lord/FBI informant Whitey Bulger in this based-on-true-events thriller, and he's joined by some equally heavyweight names including Joel Edgerton as his special agent handler John Connolly and Benedict Cumberbatch as his politician brother Bill Bulger, who went on to become president of the Massachusetts Senate. Quite the tale.

For this second teaser, however, it's all about Depp, as his bloody rise to city kingpin is plotted with an equally menacing soundtrack.

Black Mass is in cinemas from 25 Sept
