This year's Oscars is shaping up to be one of the toughest in recent years.

Although it looks like the Best Actor and Actress categories are a foregone conclusion, Best Picture and Best Director are still unclear as of yet and the various technical categories are still undecided. Without a shadow of a doubt, it's been one of the strongest performances by Ireland this year, taking in seven nominations across the categories with two in Best Picture.

Here's the full list of nominations announced today by Ang Lee, Guillermo Del Toro, John Krasinski and Academy President Cheryl Boone Isaacs.
