The site reports that negotiations have been going on all week and it seems that Vaughn beat out other directors such as Daniel Espinosa (Snabba Cash), Rupert Sanders (The Low Dweller) and Jonathan Mostow (Surrogates).

Interestingly enough, Vaughn was set to direct Fox's X-Men: The Last Stand before leaving the project. We'll be sure to keep you posted on any new developments on X-Men: First Class as soon as we have more information.
