Following in his "Avengers: Age of Ultron" co-stars' footsteps, Samuel L. Jackson has revealed the character posters for his character Nick Fury, Black Widow and Thor via Twitter. You can check out the three close-up character posters below.

The posters join two already revealed character shots of Iron Man and Hulk. Robert Downey Jr. shared his poster earlier this week followed yesterday by his co-star Mark Ruffalo. The character posters all follow the release of the official poster earlier this week, which features the entire team along with a few new recruits.

"Avengers: Age of Ultron" arrives on May 1.
