I don't know if anyone caught this but at the end Cobb's son said he was a building house out of dirt or something. Future architect maybe?
Also I was wondering about the plane flight. It's assumed everyone went to the bathroom(except Yusuf LOL)
It must have been a pretty messy airplane floor or everyone was rushing for the bathroom after waking up. Also there's restless leg syndrome and blood clots forming since they weren't moving around.
Also the music is fantastic. I already had "Mombasa" but then I got "Time"
