Thor, the Hulk and Captain America may use coarse language and shed visible blood on screen in Deadpool 3.
The upcoming sequel will be R-rated as the first two films were, but this one will be part of the Marvel Cinematic Universe (MCU), according to Marvel Studios president Kevin Feige.
That means swearing and graphic violence is possible for any of the Avengers characters who feature.
"It will be rated R and we are working on a script right now, and Ryan [Reynolds is] overseeing a script right now... it will not be [filming] this year," Feige told Collider.
"We've got a number of things we've already announced that we now have to make, but it’s exciting for it to have begun. Again, a very different type of character in the MCU, and Ryan is a force of nature, which is just awesome to see him bring that character to life."
Deadpool was previously a 20th Century Fox property and unable to join the MCU, which is owned by Disney.
That all changed when Disney bought 20th Century Fox, but there was some speculation that the family-friendly company may censor the adult content out of future Deadpool movies - speculation that Feige has now put an end to.
However, with filming on Deadpool 3 not starting until 2022 at the earliest, fans likely have a few years to wait until they'll get to see it.
