Reese looked amazing, as usual, in an outfit that epitomized her classic, clean style. The actress wore a simple black dress that highlighted her baby bump, and hot pink heels.

Matthew turned up in a white dress shirt and jacket (he didn't look too shabby, himself!) by Dolce&Gabbana.

Mud echoes Mark Twain's The Adventures of Huckleberry Finn; a fugitive (Mud, played by Matthew) is on the run after committing a crime to win the heart of Juniper (Reese). He meets two teenage boys (newbies Tye Sheridan and Jacob Lofland) who decide to help him out when they learn he is back in the area because of his love for Juniper, but all three are soon drawn into an dangerous race against time as the family of Mud's victim shows up to get revenge. The movie earned strong positive reviews at the film festival.
