The helmers said they are making sure the film is as successful as its earlier instalments, 'Captain America: The Winter Soldier' (2014) and 'Captain America: The First Avenger' (2011), reported Entertainment Weekly.
"That's what we're in the middle of on ('Captain America 3') right now, pushing really hard to make sure that what we deliver is something that's going to be different from 'The Winter Soldier'," they said.
'Captain America 3', starring Chris Evans, is scheduled for release on May 6, 2016.
