Speaking in character as Admiral General Aladeen from his upcoming movie The Dictator, Cohen quipped about his supposed ban from attending the Oscars ceremony.
Cohen was originally invited to the Academy Awards as part of the party for Hugo, which has received 11 nominations.
Admiral General Aladeen previously gave a message to the American people during this year's Super Bowl broadcast.
Cohen's The Dictator co-star Anna Faris has described him as a "comedic genius".
