The 37-year-old actor, who is starring in the film alongside former 'Downton Abbey' star Jessica Brown Findlay, said the romantic drama will not be a favourite for everybody since it is too sweet, reported Contactmusic.
"It's not for everyone. I know that for some people it will be too sweet. But it's also a very beautiful and very optimistic and very kindly intentioned film that has not a shard of malice in it, and I'm hoping that the people who will enjoy it, will really enjoy it," he said.
"That was a hairy ride, man. People can get thrown off horses, you know? And I don't mind for myself because I've been thrown off horses before, and it's fine, it's cool, you just get back on again.
"I don't even mind how wild the horse is - although the horse we used in the film was pretty cool and mellow. But I did fear riding with Jessica in the back because I'm not that good a horseman.
