Idris Elba doesn't know where to sit at the Golden Globe awards.

The 41-year-old actor is nominated for Best Actor prizes for his work on both his movie 'Mandela: Long Walk to Freedom' and TV miniseries 'Luther' - for which he won at the same ceremony in 2011 - and he is planning to keep his options open when it comes to celebrating or commiserating at Sunday's (12.01.13) show.

Speaking on 'Chelsea Lately', he said: ''The problem is there's two tables to sit on: there's a 'Mandela' table and there's a 'Luther' table. So, since I already won at the 'Luther' table, I was going to sit at the Mandela table. But if I don't win that, I'm gonna run back to the 'Luther' table and just be like, 'Hey, sorry about that, guys. I got this one.'''

Idris is currently working on an acceptance speech in case he does win because he thinks he needs to say something ''important'' if he is recognised for his portrayal of late freedom fighter Nelson Mandela.

He said: ''I've got to think about a speech, because you play someone like Nelson Mandela, you have to say something really important if you win. So, I've got to think about that.''
