Saoirse Ronan & Gemma Arterton: 'Byzantium' TIFF Premiere!

Saoirse Ronan (in Alexander McQueen) and Gemma Arterton attend the premiere of their film Byzantium during the 2012 Toronto International Film Festival on Sunday (September 9) at the Ryerson Theatre in Toronto, Canada.

After the premiere, the ladies headed over to the Grey Goose sponsored after party at the Soho House.

Byzantium is about a mother and daughter vampire duo (Arterton and Ronan) who form a deadly pact.
