Eddie Redmayne scooped another top acting award last night for his portrayal of Stephen Hawking in The Theory Of Everything - and dedicated it to those living with the scientist's condition.
The Brit beat Birdman star Michael Keaton in the most outstanding actor category at the Screen Actors Guild Awards.
Redmayne has already won a Golden Globe, but it is thought he could now score a hat trick at the Oscar's next month.
The SAGs award ceremony, held in LA last night, is widely held as an indicator as to who will win at this year's Oscar's.
In his acceptance speech, Redmayne told the audience he had learned a lot while making the biopic about Hawking, who suffers from ALS, also known as Lou Gehrig's disease.
He said: "I would like to dedicate this award to those people around the world living with ALS, to those who have lost their lives to this brutal disease.
"In preparing to play Stephen I met many people fighting ALS, and I met their families fighting alongside them. And the courage and the bravery and the spirit, this triumph of spirit that I witnessed, blew my mind. So I'm incredibly grateful to them."
There was more Brit success for Downton Abbey, who took the award for best ensemble cast in a TV drama series for the second time.
Earlier this month Downton star Joanne Froggatt won a Golden Globe for her portrayal of lady's maid Anna Bates in the critically acclaimed show.
