A Maxime Simoens-clad Rachel McAdams  joined her Midnight in Paris costars this morning for a photo call during the Cannes Film Festival. Director Woody Allen  led the group that included Owen Wilson , French actress Léa Seydoux, Adrien Brody , and Rachel's real-life leading man Michael Sheen. Rachel and Michael are together in France after a stint in LA, where they promoted the movie at a press junket. There was time for Rachel and Michael to hang out with his daughter, Lily Sheen , though Rachel was also spotted running errands solo. Their big screen project opens in the US in limited release later this month on the 20th, and many Midnight in Paris reviews  are so far positive.
