Jason Sudeikis was worried about how he was going to pronounce the names of the nominees at the Academy Awards.

The 38-year-old actor - who walked the red carpet with pregnant Olivia Wilde - had a piece of paper with the phonetic breakdown of names in the Best Live Action Short Film category to ensure he didn't mess up when he took to the stage at the at the Dolby Theatre in Hollywood, Los Angeles.

He told E! News: ''There's letters in here that aren't even in the alphabet. ''There's an ampersand in the middle of this. So I'm just as nervous as anybody nominated.''

The winner of Best Live Action Short Film was 'Helium' by Danish filmmaker Anders Walter and Kim Magnusson.

Other nominations in that category included 'Aquél no era yo' (That Wasn't Me), 'Avant que de tout perdre' (Just Before Losing Everything), 'Pitääkö mun kaikki hoitaa?' (Do I Have to Take Care of Everything?) and 'The Voorman Problem'.
