The Thor star is currently in Europe promoting his latest picture, Snow White And The Huntsman, and he attended the film's premiere in London on Monday (14May12), just days after the birth of India, his first child with his wife Elsa Pataky.
However, the actor admits he is battling through sleepless nights at home but is determined to carry on working.
Hemsworth tells the Press Association, ""The last few days has been a bit of press, and then I'm at home with the baby and trying to get some sleep in there, which hasn't been happening. But it's fantastic. I'm running on adrenaline at the moment, and it's all wonderful.""
