Andrew Garfield might not be Spider-Man much longer

Sony has already announced their intentions to run their terrible Amazing Spider-Man movies into the ground with at least four movies total. However, we have some speculation regarding the casting of the most important character. Andrew Garfield, who has been contracted through a third Amazing Spider-Man, recently discussed the future of the franchise and made his uncertainty about playing Spider-Man for four movies.

Release years have already been announced for the third and fourth. The Amazing Spider-Man 3 will hit in 2016 with The Amazing Spider-Man 4 hitting in 2018. During an interview with Yahoo! Movies, Garfield had this to say:

"I mean I’m under contract for another one after this… as far as a forth one? That’s not anything to do with me."

This could mean a couple things. First off, by the time 2018 rolls around Garfield will be 35. That's a bit old for a teenage hero if you ask me. Tobey Maguire wasn't even that old when Spider-Man 3 came out in 2007. Second off, I imagine Garfield doesn't want to just be known for playing Spider-Man. Granted he got pretty famous for The Social Network, but what has he done since? Well, other than play Spider-Man. The answer is nothing notable. This doesn't surprise me one bit. I wouldn't even stick around through the third one, but that's just me. I don't even think Garfield is a good Spider-Man.

Sony confirms The Amazing Spider-Man 3 & 4

Sony is rolling along with their recent, and rather successful, reboot of Spider-Man. Seeing that The Amazing Spider-Man raked in over $750 million in 2012 and the is sequel currently in production, they have announced the release dates for The Amazing Spider-Man 3 and 4. We will get the third installment on June 10, 2016 and the fourth on May 4, 2018.

The details for each movie are non-existent and the sequel is still being filmed in NYC, so I wouldn't expect any more information for quite sometime. However, certain cast and crew members (specifically Andrew Garfield) have signed multi-year deals so it's pretty obvious that they will be sticking around until 2018. This also pretty much confirms that Sony is clinging onto the rights to Spider-Man, so those wishing for the Spidey cameo in a future Avengers movie can stop holding their breath.

We also have some new characters that are rather important to the Spider-Man story that will be introduced in The Amazing Spider-Man 2 such as Mary Jane Watson (played by Shailene Woodley) and Harry Osborne (played by Dane DeHaan). I have no doubt one or both of them will have a major part in the future Spider-Man movies Sony has just announced. 
My only concern with this is Andrew Garfield's age. He's already 29 and is portraying a 17-year old. By the time 2018 hits he will be pushing 35. That is a bit ridiculous.
