Koimoi.com brings you the Hollywood releases this week (October 21):
Paranormal Activity 3

In 1988, young sisters Katie (Katie Featherston) and Kristi (Sprague Grayden) encounter an invisible entity haunting their home. Although it appears friendly, it turns hostile, tormenting the young girls and their family.
The Whistleblower

Inspired by actual events, Kathy (Rachel Weisz) is an American police officer who takes a job working as a peacekeeper in post-war Bosnia. Her expectations of helping to rebuild a devastated country are dashed when she uncovers a dangerous reality of corruption, cover-up and intrigue amid a world of private contractors and multinational diplomatic doubletalk.
Last Night

Last Night centers on a married couple apart for an evening when the husband (Michael Reed) takes a business trip with a colleague (Eva Mendes) to whom he’s attracted. While he’s resisting temptation, his wife (Keira Knightley) encounters her past love (Guillaume Canet). Last Night is ultimately a film about choices— the choice you make to be with someone, to give yourself to someone physically, to open yourself emotionally, and how to survive all three.
