Lots of movie casting news these days — from Marley and Me to aliens lurking upstairs.

• Alan Arkin will join Jennifer Aniston and Owen WIlson [1] in the film adaptation [2] of bestselling memoir Marley and Me [3]. Wilson plays a newspaper columnist who adopts a dog with his wife (Aniston). Arkin will play the editor of the newspaper.
• Jessica Biel will star as the lead in the romantic comedy Easy Virtue [4], based on the Noel Coward play. The movie follows Biel's character, "an American divorcee who travels to the South of France and marries a young Englishman, played by Ben Barnes, on the spur of the moment. The couple return to England to face his family, including his parents, played by Colin Firth and Kristin Scott Thomas."
• Amy Ryan is the lucky lady chosen to star opposite Matt Damon [5] in an untitled Iraq war thriller directed by Paul Greengrass, the director of two of the Bourne movies and United 93.
• High School Musical star Ashley Tisdale will make her feature film debut [6] in "the adventure comedy" They Came From Upstairs about "a group of teens who have to defend their Maine home from the aliens who invaded the top floor." Just the top floor? Huh.
