'Pacific Rim' actor spends 27 days straight on cross-trainer to film scenes

Charlie Hunnam spent 14 hours a day, for 27 days, on a cross-trainer while filming 'Pacific Rim'.

The 33-year-old actor - who plays pilot Raleigh Becket in Guillermo del Toro's sci-fi blockbuster - had to muster all his strength while on set as some scenes required him to use the exercise machine for hours at a time.
