I poked around and James Earl Jones has also been in 4 baseball movies.
The Sandlot
The Sandlot 2
Field of Dreams
The Benchwarmers
... shown with his appearances in both Firld of Dreams andThe Benchwarmers.
Although in The Benchwarmers, he is only credited as Darth Vader (voice). Not sure if he is actually in the movie or they just have a clip from Star Wars or what. And no quarantine is long enough to make me watch that movie...
