Diet Coke or Pepsi?

I was watching Batman 1989 yesterday and noticed this Pepsi can in the background. I thought Diet Coke was the pop that endorsed Batman.
Or was that only for the videotape release?

Looks like it's in a trash pile, where Pepsi belongs.

So that's where I put it!

I remember reading a that technician left his pepsi can in the Batwing wreckage as a joke to see if anyone noticed, maybe it wasn't so random. Dominoes Pizza famously won the bid to be in the Ninja Turtles movie yet the VHS opened with a Pizza Hut commercial.
