A Perfect Getaway (2009)

Hawaiian-set thriller from 'Pitch Black' director David Twohy, starring Steve Zahn and Milla Jovovich. When newlyweds Cliff (Zahn) and Cydney (Jovovich) head off to Hawaii's remotest beaches for their honeymoon, they believe they've found paradise on Earth. However, when they meet a group of scared hikers who inform them of the gruesome murder of another young married couple, they begin to doubt their original assessment. Teaming up with two other couples seems like the safest way to go, but when you don't know who to trust, everyone is a threat. It's not long before an adventurous, romantic honeymoon turns into a bloody battle for survival. Timothy Olyphant, Chris Hemsworth, Marley Shelton and Kiele Sanchez co-star.
