On paper, landing a role in Castle and Hughes' Dennis the Menace film adaptation was a huge career move for a child actor. The comic strip is beloved by many and there were a handful of seasoned thespians alongside which to work. For Hank Johnston, the opportunity never really paid off, as the 1993 family comedy was arguably the biggest role he landed in his very short acting tenure. Be it by personal choice or lack of offers, he can count all of his credited film and television works on one hand.

Following Dennis the Menace, Johnston managed to land a spot in 1994's Miracle on 34th Street, although the role was not very substantial. His character didn't even receive a name — it's labeled on his IMDb page as simply "Boy." From there, he got a recurring spot on the incredibly short-lived police drama Turks, on which he played Don Jr. for four of its 13 episodes. As of this writing, his last noted work was in the 2001 drama Madison as Ricky, another minor part. It's been 19 years since Johnston last put his acting chops to the test, so it suffices to say a career resurgence is unlikely at this point.
