Scarlett Johansson, Eva Longoria speak at Democratic Convention: watch

Scarlett Johansson has spoken at this year's Democratic National Convention.

The Avengers actress took to the dais in North Carolina to express her support for President Barack Obama's re-election campaign.



Eva Longoria and Kerry Washington also appeared on the final night of the DNC, although Natalie Portman was not involved despite an earlier leaked lineup including her on the schedule.

Johansson encouraged those who are not interested in politics to "vote so that your voice is heard", adding: "Get out there. Exercise your right to vote."

Longoria, who serves as a co-chair for Obama's re-election campaign, praised the President's understanding of "the value of American opportunity".

"President Obama is fighting for changes that grow the economy from the middle out and help all Americans succeed," she said.

"He is moving us forward with opportunity today for prosperity tomorrow. [Republican candidate] Mitt Romney wants to take us back to yesterday."

Longoria previously described her address to the crowd as "probably the most important speech [she's] ever done".
