There is an upcoming film 'The Avengers' with a release date of May 4, 2012 . If you are referring to the 1960s 'The Avengers' there was a 1998 film of the same name starring Uma Thurman based upon the TV series .
In 2009; Avatar became the biggest money making film of all time.
Different characters have drifted in and out of the Avengers line-up over time. Steve Rogers, also known as the original Captain America, was among them. He will also appear in the Avengers line-up in the upcoming Avengers film.
As of May 01st 2018, The Avengers is currently the fifth highest grossing film worldwide & the sixth domestically. Given the huge opening weekend success of Avengers Infinity War, The Avengers will most likely move down a notch in both lists. Time will tell.
No: Avengers is Marvel and Justice League is DC so they cant be in a film together
