Helen Mirren's portrayal of The Queen is movie fans' favorite royal role, according to a new online poll.

In anticipation of Colin Firth's Best Actor win at the Golden Globe Awards on Sunday for The King's Speech, and his assured Oscar nomination, websites WENN and Fandango.com staged a weekend vote to find the best movie monarch.

Mirren topped the poll with 47 per cent, while Cate Blanchett's Elizabeth I came in second with 31 per cent of the vote.

Judi Dench came in third and fourth with her portrayals of Elizabeth I (Shakespeare in Love) and Queen Victoria (Mrs. Brown), and Nigel Hawthorne rounded out the top five with his role as King George III in The Madness of King George.
