Apparently, a character in a current movie, Crazy Rich Asians is an economist. Dan Kopf considerswhether she is a good economist. In a couple of recent tweets, Paul Krugman reacts:

"Actually, I can fill this gap.

"There was a movie titled The Internecine Project ... with James Coburn as a chairman of the Council of Economic Advisers who gets a bunch of people to kill each other to hide his evil past. Sounds good to me, but the movie was terrible." -- Paul Krugman, 9 August 2018

I do not know about the movie versions, but I can name a couple of book series with characters who are economists:

  • Meyer is the sidekick in John D. MacDonald's Travis McGeemystery series. Meyer's houseboat is the John Maynard Keynes, until it is blown up. He replaces it with the Thorstein Veblen.
  • The love interest in the Bourne Identity series is an economist. If I recall correctly, Jason Bourne first meets her by carjacking and kidnapping her, and then forcing her to drive with him to Paris.

I don't think you can count the Marshall Jevons' mystery series, since that is a pen name for two economists.
