Geez, what was the time frame here???
OK am I the only one who notices that there don't seem to be any lapses in time - except for the overnight jump after R2's escape from the farm. Everything seemed to happen in real time. They gave no indication otherwise. So from the time Luke searches for R2, he gets pummeled by the sandpeople, rescued by Obi Wan, his family gets killed, they head to Mos Eisley, meet Han and Chewy, learn the ways of the Force, get captured at the Death Star, escape from it and destroy it.
All in a day.
I cleaned the living room, had a sandwich, did laundry and played with my cat.
