So I was reading up on Avengers trivia and apparently RDJ kept food hidden all over this set and they couldn’t find where it was so they just kinda let him continue doing it. So that’s his actual food he’s offering and whenever he’s eating in a scene, it’s not scripted. He was just hungry.
The waters of Arnensee in Switzerland are so clear they cause boats such as the one in the picture to appear as they are hovering in the air.
The lake is located in Canton of Berne in Switzerland, and can be easily reached with a little planning. Although that first picture has made the lake relatively known, it’s still usually a quiet, tourist-free place.
