Horrible Histories film: Cast tell us what to expect

Did you know there was a brand new Horrible Histories film out?

The film's theme is Rotten Romans and Newsround has been speaking to two of the film's stars.

Sadly Rattus Rattus wasn't available for interview, but we did get to hear from Emilia Jones and Sebastian Croft, who play Roman teen Atti and young Celt Orla in the film.

So what secrets did they reveal?
