On top of the news that Tim Blake Nelson is returning as The Leader (Samuel Sterns), rumors are now emerging that are indicating that Mark Ruffalo could also be reprising his role as the Hulk in Captain America: New World Order.

If Ruffalo does appear in the Anthony Mackie-led Marvel film -- where the fourth Captain America will see Sam Wilson sporting the red, white, and blue uniform -- this would be a good chance to tie in the 14 years of Hulk history with the original Samuel Sterns facing off against Ruffalo's take on the Hulk/Bruce Banner.

Fans should not get too excited just yet as Ruffalo has allegedly only entered talks in considering the role.
