According to a report from the Wall Street Journal, Spider-Man will indeed be appearing in Captain America: Civil War. This was the obvious choice as the original press release said Spider-Man would appear in a Marvel movie prior to the release of the next solo Spider-Man movie on July 28th, 2017. The only Marvel films that would work for that were the already completed Avengers: Age of Ultron and Ant-Man… so those are a no. The sequel to Guaridans of the Galaxy… Spidey in space is a no. Doctor Strange… doubt they'd put him in another characters debut. So that left only Civil War.
They are also reporting that with Spider-Man being back on the film schedule, the Sinister Six film is going to be delayed which had been scheduled for November 2016. No new date was given.
And finally, they are saying that Andrew Garfield is out. The 31-year old actor was said by some to be too old to play the high school student and others claimed the character was more angsty than Peter Parker was supposed to be… but I liked him in the role and would have been fine with him continuing, but if the report is true then we can expect a new casting announcement on the horizon.
