The Big Bang Theory has filled our lives with 11 seasons of joy, laughter, tears, and given us a love for science (well what we can understand of it). The show is the perfect series to sit back, relax, and simply enjoy at the end of a long day. The show first debuted in 2007, it soon became the highest-rated comedy series. We decided to have a look at just how much the actors and actresses have evolved over all 11 seasons. It is quite astounding to see just how different the cast is off-screen, you may not even recognize them…
John Galecki as Leonard Hofstadter
You may know him as the shy David Healy from Roseanne but you definitely know him as Leonard Hofstadter, physicist and geek from The Big Bang Theory. John Galecki is now 45-years old, married, and has a child. He recently acted in the reprise of the Roseanne mini-series but fans were still happy to see him.
