Hey! I recently watched a dumb movie called “Robo-Dog” from 2015 and there was a scene in which the protagonists played SuperTuxKart. The scene is ca. 19 seconds long.
They are playing an old version of STK, obviously, it's the Shiny Suburbs track with Elephphant, played on 2-player split screen.
The scene starts at ca. 1:01:34.
But the scene doesn't really make sense, at the end, one player says “I won!” although they weren't even close to the finish line. It's not an important scene anyway, it's just a placehoder for videogaming that is unimportant to the plot. Whatever. I told you it was a dumb movie.
I wasn't able to find STK in the credits, however. Not that I really care. :P
You can see the movie in German here: https://www.youtube.com/watch?v=Z3Jkg6uiVCo
