Orlando Bloom Goes Bad In 'The Good Doctor' Trailer (VIDEO)

You'd think having Orlando Bloom as your doctor would be great, but as the trailer for his latest film shows, it might not be such a blessing.

The Lord of the Rings actor features in Lance Daly's thriller as Dr. Martin Blake, a young doctor who begins to use drugs for all the wrong reasons.

In the trailer, Bloom meets an 18-year-old patient named Diane (Riley Keough) and gets a much-needed boost of self-esteem.

However, things turn dark as he begins tampering with Diane's treatment to keep her sick and in the hospital right next to him.

And if you think Riley Keough looks strangely familiar, that's because she's got the showbusiness genes in her. She's the grand-daughter of one Elvis Presley, the daughter of Elvis's only child Lisa Marie and her ex-husband Danny Keough.

The Good Doctor will debut on 31 August in the US. A UK release is yet to be confirmed.
