39. Michael Maronna

Many nostalgic ’90s kids will probably recognize Michael Maronna instantly from the popular Nickelodeon show The Adventures of Pete and Pete. On the show, he played Big Pete. He also played Jeff McAllister in the 1990 hit Home Alone and its sequel.
However, Maronna has since managed to establish a different sort of career for himself. He currently works as an electrician and has assisted on the sets of such projects as Nurse Jackie, Notorious, and Sex and the City. So, while we may not see him on screen anymore, he has remained deeply connected with Hollywood and helps keep its lights twinkling.
