Jessica Biel, Kate Beckinsale, and Colin Farrell are busy in London with their Total Recall promotional duties. The costars arrived separately for a private event last night, when Jessica tweeted a picture with the caption, "Hilarious panel with my cast and director." They were back to work this morning. Jessica made a fashionable visit to Kiss FM radio, while Kate and Colin swung by BBC Radio. The Total Recall stars have spent a lot of time together recently. They were in LA and NYC last week, then headed overseas to kick off the European portion of the tour. Kate, Jessica, and Colin went to Berlin before debuting the film in Dublin earlier this week.
