7. Quantum Leap
He can change the world
This series, which ran from 1989 to 1993, featured Scott Bakula (pictured) as a character with the literary name of Dr. Samuel Beckett. The good doc gets stuck in a time travel experiment gone awry, and he lands in other times in other peoples bodies (even though he still looks like Bakula to us). He becomes a fixer through the ages, righting wrongs in strangers lives and mixing it up with famous and not-so-famous historical faces from Buddy Holly to Dr. Ruth Westheimer.
