Celebrities have been expressing their condolences after Star Trek actor Anton Yelchin died at the age of 27.
The actor - best known for playing Chekov in the rebooted sci-fi films - was killed when he was struck by his own car as it rolled backwards down his driveway.
His Star Trek co-stars Zachary Quinto and John Cho - and director Justin Lin - are among those who have paid tribute to the actor on social media.
Zachary posted a picture of Anton on Instagram.
He wrote: "our dear friend. our comrade. our anton. one of the most open and intellectually curious people i have ever had the pleasure to know. so enormously talented and generous of heart. wise beyond his years. and gone before his time. all love and strength to his family at this impossible time of grief."
