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," dailystar.co.uk 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.
