Porto???

Not sure, I never noticed he wasn't in it.


"They've done studies, you know. 60% of the time, it works every time."

My guess would be that since the PR series relies on using Super Sentai footage for the monster fights, the fact that Porto was in the Super Sentai footage meant that it required his appearance in the series. The movie was 100% American-made so they just wrote and included the villains they thought were important.
