I don't like that Iron-Spider thing either. I hope its only for Infinity War.
MCU has simply given up this secret ID thing. Remember the end of Homecoming. Sad to see this. Though i loved them interacting like that.
Hugh Jackman played the role for 17 years. 2000 the first X-Men to Logan in 2017. RDJ might still want to continue. Its not a very difficult job like say Bond which involves a lot of physicality. And he keeps getting that kind of money.
