Stephen McFeely has revealed that they are on the third draft of the first Avengers: Infinity War movie and the second draft of film two.

The upcoming Avengers movies are already highly anticipated and will see McFeely reunite with Christopher Markus to write both screenplays.
It has been revealed that they will now be two stand alone movies with two different titles, McFeely has revealed that the screenplays are being written in tandem.
Speaking to Yahoo! Movies, McFeely said: "We're many drafts in. We're on the third draft of movie one and the second draft of movie two. [We're writing them in tandem] as much as we can. On any given day, you're only working on one but that doesn't mean that next week, you aren't working on the other one.
"And certainly, notes are coming in and all sorts of production stuff is coming in, like for instance, 'that thing over there is now a window not a door so adjust that.' Or, 'we're not going to this town now, we're going to this town.' That kind of stuff happens constantly and will continue to happen for the next few months."
McFeely and Markus have already penned the screenplays for Captain America: The Winter Solider and Captain America: Civil War and the Avengers films will see them reunite with filmmakers Anthony and Joe Russo.
Markus went on to say that both films are connected and they started out by establishing which characters were still alive inside the MCU.
He said: "When we lock ourselves in a room with the Russo brothers and a couple of execs from Marvel, one wall has cards for movie one and the other wall has cards for movie two and another wall has little baseball cards of every character still alive in the Marvel universe - down to Darcy's boyfriend in Thor 2 - literally, anybody who did not die and has been established as alive.
"And then we looked at that began to shuffle the cards around. So basically, the big scene is when Darcy's boyfriend and Galactus get together and...[laughs]."
The cast for the upcoming Avengers movies has not yet been revealed but filming is expected to get under way early next year.
While Anthony and Joe Russo are no strangers to the MCU - having steered the last two Captain America films to critical and commercial success - it will be the first time that they have directed an Avengers film.
But we have a whole host of MCU movies to be released before Avengers: Infinity War as Doctor Strange, Guardians of the Galaxy Vol 2, Spider-Man: Homecoming, and Thor: Ragnarok are all on the horizon.
Avengers: Infinity War is released 27th April 2018.
