London: American actress Zoe Saldana says she was left emotionally and physically exhausted for a year after the release of sci-fi epic "Avatar".
"The year after `Avatar` was just emotionally overwhelming. I was travelling all over the world, waking up in different time zones. Your body gets exhausted, and by the end of the year I just collapsed," a website quoted her as saying.
Saldana`s upcoming projects include "Colombiana" and "Infinitely Polar Bear".
"I was sitting in my hotel room, and I couldn`t stop crying. I couldn`t stay awake. I must have slept for an entire month. It took me the rest of the year, even as I was working and shooting `Colombiana`, to pick myself up. Thank God my family was there," she added.
