The Real Reason Mary-Kate And Ashley Olsen Landed Their Full House Roles

Mary-Kate and Ashely Olsen were nine months old when they first starred in "Full House." Despite not crying much in the audition, their nature as babies soon shone through on set, nearly getting them fired. "It's sort of true that the Olsen twins cried a lot," co-star John Stamos told Entertainment Weekly in 2015, admitting that he asked for them to be replaced. "It was very difficult to get the shot." They were replaced with another set of twins for a while to see if that would work, but the Olsens were soon back on set.

But after the first season ended, they were nearly pulled off the show by their parents. "We were worried whether it would be too disruptive to them and the rest of the family," their dad Dave Olsen told TV Guide in 1993 (via Fanpop). "But Mary-Kate and Ashely really enjoyed being there, and we eventually decided that as long as they were having fun we'd let them keep doing it."
