There are plenty of TV shows that don’t need to be remade. Sally Field’s ’60s sitcom “The Flying Nun’’ and the “Happy Days’’ spinoff “Joanie Loves Chachi’’ are two that come immediately to mind. Another might be “Highway to Heaven,’’ the ’80s show starring the late Michael Landon as an angel sent to earth to help troubled souls overcome their issues. To be fair, the show did last for five seasons, so someone must have liked it. Mark Wahlberg may have been one of them because the actor/producer is partnering with A&E to remake “Highway to Heaven.’’ (John Wirth, whose credits include AMC’s “Hell on Wheels’’ and the short-lived Fox series “Terminator: The Sarah Connor Chronicles’’ is on board as writer.) Perhaps we shouldn’t be surprised that the actor/producer formerly known as Marky Mark is involved. The show’s religious overtones likely appeal to Wahlberg, who’s become a devout Catholic and regular church-goer.
