Martin Scorsese and Leonardo DiCaprio both had the biggest openings of their careers this weekend, with Shutter Island bringing in an estimated $40.2 million. The creepy thriller soared to the top of the box-office charts, beating out last week’s winner Valentine’s Day, which made $17.6 million, and Avatar, which brought in $16.1 million and is now only days away from hitting a $700 million domestic gross.
