For those worried that Black Widow and Captain America didn't have enough to do in Avengers: Infinity War, you're in for a treat with Avengers 4.

In an interview with The New York TimesInfinity War and Avengers 4 screenwriters Christopher Markus and Stephen McFeely said the two heroes will be much bigger players come next year's event film.

Black Widow and Captain America spent much of Infinity War guarding Vision and his Mind Stone from the hands of the Black Order, eventually leading to a final showdown with Thanos in Wakanda. Captain America had a few lines about not "trading lives" and Black Widow had some major action scenes, but as far as the major plot went, the two weren't a huge part of it.

Markus said they “have a much bigger role to play in that second film.”

And while Marvel Studios itself has backed away from the "Part One" and "Part Two" nature of the films' titles, Markus said Infinity War was still planned with its follow-up in mind.

“We gave ourselves license to pay off later,” he said.

With the original, core Avengers team still intact going into Avengers 4, and the debut of heroes like Captain Marvel on the horizon, there's no doubt the film will try to make good on these promises. With what looks like a smaller cast, expect less one-liners and more getting stuff done.

Directed by Joe and Anthony Russo, Avengers: Infinity War stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Mark Ruffalo, Jeremy Renner, Scarlett Johansson, Anthony Mackie, Paul Rudd, Elizabeth Olsen, Tom Holland, Benedict Cumberbatch, Chadwick Boseman, Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper, Vin Diesel, Tom Hiddleston, and Josh Brolin.
