“Inception” tie to Lost

Hey everybody,
Just wanted to say, I saw the movie Inception Sunday night, and I was very impressed. I watched it with a bunch of my friends, alot of them being Lost fans. There’s a point in the movie where somebody’s father is in a coffin, flying from Sydney to LAX, and the son is also on the flight.. All of my Lost friends and I were like, that’s definitely a shout out to Lost!! It’s not pertinent to the plot, so why put something like that in there unless they did that on purpose to coincide with Lost?!
