First off I'd like to say I am very exited to see spidey join up with the avengers, but in order to do that we have to make some sacrifices. I liked Andrew Garfield's The Amazing Spider Man movies, even with its quirks. Because Garfield is not a candidate I will not include him in this list.
SO HERE WE GO!
1: Thomas Brodie-Sangster
I think Thomas Brodie-Sangster is a great actor, and would be a great fit (he is my choice)
You may recognize him for his Oscar winning role as Steven Hawking in "The Theory of Everything." He's got the nerd part down.
3: Anton Yelchin
This Actor is very versatile, ranging from Star Trek to Charlie Bartlett.
4: Tye Sheridan
This guy has it in the bag. He is an amazing actor and if you haven't seen his work please watch Mud (2012) or Joe (2013).
5: Daniel Radcliffe
6: Freddie Highmore
∞: Nicolas Cage
Just kidding about that last one.
These are my Top 6 choices. I know that Dylan O'Brien has been considered, i have just never cared for him. Let Me know what you think!
Im just a HUGE spiderman fan and want them (more than anything) to get this one right.
