Hollywood once again hosted last night the Academy Awards, the night that rewards films, actors, actresses, directors and other movie professionals for their work.

This year's best picture went to 12 Years of Slave, as many expected, while Gravity got the Best Directing award and several ones in the more technical categories. The 2 main actors for Dallas Buyers Club won the awards for Best Actor in a leading and in a supporting role, while Lupita Nyong'o and Cate Blanchette were the 2 ladies of the night. Let's notice that Wolf of Wall Street, that many expected to win, didn't take back home any statuettes.

The ceremony was presented again this year by Ellen Degeneres who posted a group selfie picture, now the most retweeted post of all time:
