Blu-ray Movie Releases for May 24, 2011 includes “I Am Number Four” (2011). From Director D.J. Caruso (Disturbia), producer Michael Bay (Transformers) and the Emmy-winning writers of TV’s Smallville, comes this gripping, action-packed thriller. John Smith (Alex Pettyfer) is an extraordinary teen masking his true identity to elude a deadly enemy sent to destroy him. Also new this week is “The Great Dictator” (1940). In his notorious masterpiece, The Great Dictator, Charlie Chaplin (City Lights, Modern Times) offers both a cutting caricature of Adolf Hitler and a sly tweaking of his own comic persona. Chaplin (in his first pure talkie) brings his sublime physicality to two roles: the cruel yet clownish “Tomanian” dictator and the kindly Jewish barber who is mistaken for him. Other new releases include “The Big Bang” (2011), “Gnomeo & Juliet” (2011), Andrei Tarkovsky’s masterpiece “Solaris” (1972) and “Gettysburg: Director’s Cut” (1993).
