We're delighted to announce that one of those cast members is none other than the legend himself, Phil Daniels, star of the cult classic, Quadrophenia and more recently Eastenders, Misfits and Rock & Chips.
As he came out of the recording session, Phil told us, 'It was great to do! You get to go through the gunpowder plot in various ways...' He pauses, not wanting to reveal too much. 'It's really interesting... It'll be fantastic!'
Phil, of course, also provided a voice on Blur's 'Parklife' single & was seen alongside Damon Albarn in the video.
If you are unfamiliar with his work you can find out on his IMDB page.
