Joel Silver's Dark Castle Entertainment has set a summer start date for "RocknRolla," an action comedy that Guy Ritchie wrote and will direct. Production will begin in London in seven weeks.

Pic harks back to Ritchie's early films "Lock, Stock and Two Smoking Barrels" and "Snatch," fast-paced dramas that had strong ensembles, attitude and low budgets. In "RocknRolla," a Russian mobster orchestrates a crooked land deal, putting millions of dollars up for grabs and attracting all of London's criminal underworld. A dangerous crime lord, a sexy accountant, a corrupt politician and a band of petty thieves are among those double-crossing one another. Pic's budget will be under $20 million.
