Tilda Swinton doesn't ''feel like'' an actress.

The 'The Grand Budapest Hotel' star - who won an Academy Award for her portrayal of ruthless lawyer Karen Crowder in 'Michael Clayton' in 2007 - can't relate to other actors when they discuss their craft.

She told variety.com: ''I don't know what it would take for me to feel like one [actress]. I understand it's a strange thing to say because I do keep saying, 'Yes, I'll dress up and be in your film.' But when I hear proper actors talking about their lives and how they approach their work, I feel like I'm up another tree.''

Swinton - who spends a lot of time in the Highlands of Scotland - isn't able to answer how she prepares for roles after she's been cast in a film.

She explained: ''When people ask about how I approach a character - well, I wouldn't know how to approach a character if I tried.

''People will ask about choosing a role - I don't choose roles. People will talk to me about preparation. Aside from putting together a disguise, I'm not aware of any preparation at all.''
