Benedict Cumberbatch's two Screen Actors Guild (SAG) Award nominations are an ''amazing early Christmas present''.

The 38-year-old star - who's been nominated for Outstanding Male Actor in a Leading Role for 'The Imitation Game' and for the Outstanding Performance by a Male Actor in a Television Movie or Miniseries for 'Sherlock: His Last Vow' - is thrilled to be in line for the prestigious awards.

He shared: ''I'm over the moon. And so delighted to receive recognition in such esteemed company for both 'Sherlock' and 'The Imitation Game' by my acting peers.

''What an amazing early Christmas present! Thank you to all who voted and watched both pieces of work.''

Keira Knightley, Benedict's co-star in 'The Imitation Game' has been nominated for the Outstanding Female Actor in a Supporting Role prize and is ''honoured'' to be up for both that award - which she will contest with Meryl Streep, Patricia Arquette, Emma Stone and Naomi Watts - and Outstanding Performance by a Cast in a Motion Picture with her castmates.

She said: ''Thank you so much to the Screen Actors Guild. It's such an honour to be nominated by your peers and in the company of this group of talented women. I'm thrilled to celebrate this morning with Benedict Cumberbatch and the cast.''

Elsewhere, Hollywood superstar Jennifer Aniston has been nominated for the Outstanding Female Actor in a Leading Role award for her performance in 'Cake', in which she plays a woman who manages her chronic pain with illegal drugs and feels ''blessed'' to have gained recognition.

The 45-year-old actress said: ''This is the best 6:00am wake up call ever.

''Words can't describe how blessed I feel to be recognised like this by my peers for this film. What an enormous feeling of joy and gratitude.''

The SAG Awards will be held on January 25, 2015 in Los Angeles.
