There is some good news for avid Marvel fans. The first trailer for the upcoming blockbuster, Avengers: Infinity War, which will unite all the MCU superheroes, will come out in early December, according to a new report.

That's not all. We finally have an exact date on when the trailer will come out. Jeremy Conrad, former editor of IGN, broke the news writing on Twitter, "Looks like the early December Infinity War trailer date is confirmed."

Replying to a fan query, Conrad noted that it will be released before Star Wars: The Last Jedi. "Online around the fourth, in theatres with Star Wars," he tweeted and later also confirmed that his news is "legit".

Explaining his disclosure about the release date, he wrote, "The exact date for the online release was floating around for a couple days. Was unconfirmed until the leak confirmed the trailer is out there."

Conrad responded to a fan, who cited another tweet from SuperBroMovies, who named Monday, 4 December as the trailer drop date. "That's the correct date. Didn't post it because I was asked not to put out the exact day," Conrad wrote.

After being pressed about his unnamed source, Conrad explained, "It's so funny people demanding someone to out sources and get them fired when they don't want to believe a scoop."

Looks like Disney previously showed the first Infinity War footage to fans at D23 and then at the San Diego Comic-Con in July, which was subsequently leaked online. Actor Paul Bettany, who plays all-powerful Vision in MCU, has teased that the Infinity War trailer will be worth the wait.

Bettany revealed he watched the trailer on co-director Joe Russo's phone, and called it "badass" and "amazing". Teasing when will it come out, he added, "It'll be out, everyone will love it."

Sebastian Stan, who plays Winter Soldier in Captain America movies, had high praise for the film. "Almost every scene is epic," he said. Avengers: Infinity War is scheduled to release on 27 April in the UK and on 4 May in the US.
