Big Bang Actors To Earn $1M Per Episode

Cludge (981852) writes with a snippet from the BBC: "And rich they will be: With The Big Bang Theory commissioned until 2017, the show's three biggest names, Jim Parsons (Sheldon), Johnny Galecki (Leonard) and Kaley Cuoco (Penny) are guaranteed to earn $72m (£42.6m) each over the next three seasons. Unsurprisingly, the cost of producing the sitcom has spiraled." I wonder what that works out per line?
