Naomi Watts voted Forbes' most bankable actress

The 'King Kong' actress has topped the magazine's latest online Best Actresses for the Buck list after proving movie bosses can make the most money from her.

The 41-year-old beauty who has also starred in 'The Ring' and 'Eastern Promises' apart from 'King Kong' helped the box office rake in an estimated $44 for every $1 she was paid for her last three major films.

The list's top spots are notably filled by many actresses willing to accept a lower salary than A-list stars like Angelina Jolie who was named Hollywood's highest-earning actress by Forbes earlier this year.

'Requiem For A Dream' actress Jennifer Connelly, 38, took second place making an average $41 per dollar she was paid while 30-year-old Rachel McAdams finished third by turning low-budget films like 'Red Eye' and 'The Notebook' into significant hits. For every dollar she is paid, the 30-year-old actress makes movie bosses an average $30.

Other stars featured on the list include Natalie Portman, who earned $28 per dollar, Meryl Streep at $27 and Jennifer Aniston at $26.

Most actresses on the list didn't carry their films alone and were often joined by a host of famous co-stars.

Connely's appearance in 'He's Just Not That Into You', in which she starred alongside Aniston, Ginnifer Goodwin, Ben Affleck, Drew Barrymore, Bradley Cooper and Scarlett Johansson, raked in $177 million at the box office, while Watts was joined by British actor Clive Owen in 'The International' (2008).
