With the new trailer for the fourth 'Avengers' confirming the title - 'Avengers: Endgame' - you'd imagine that Disney's already locked down the domain name. Right?

Wrong. If you go to avengersendgame.com, you're brought to the official website for 'Once Upon A Deadpool', the upcoming PG-13 version of 'Deadpool 2' that's in cinemas on December 12th.

As it turns out, a guy on Twitter with the account @AGuyInChair bought the domain names avengersendgame.com and avengersendgamemovie.com on April 27th, which was the day 'Avengers: Infinity War' opened.

In a tweet sent yesterday, the account offered to hand back the domain names to Disney in exchange for premiere tickets to 'Avengers: Endgame' in April.

So far, nobody from Disney has responded publicly to his request and it looks like nobody from the cast of 'Avengers: Endgame' have done so either. As the Twitter user has told TheWrap and several other outlets, he's happy to turn the domain names over to Disney if they give him premiere tickets - but so far, nothing.

And the domains are still pointing to 'Once Upon A Deadpool', which is just... incredible.

'Once Upon A Deadpool' hits Irish cinemas for one night only on December 12th and 'Avengers: Endgame' arrives on April 26th, 2019.
