This gif is kinda funny, cause if you look in the background you can clearly see Mark and his son, with his son pulling on his fathers arm while looking at Tom. Clearly Marks son is a big fan of Loki/Tom LOL So cute!!!!!
Apparently, Mark Ruffalo’s son was continuously visiting the set because he wanted to see Tom, and could when he was watching him act, simply could not get enough of Loki! I don’t blame him. This kid has good taste.
