CONCORD (CBS SF) — Parents taking their kids to see the new “SpongeBob” movie at a drive-in theater in Concord may be in for a surprise when they see what’s playing on the theater’s other screen a short distance away.

Yes, the drive-in is a slice of Americana, but at the WestWind Solano Theaters the marquee is lit up with one of the oddest pairings in cinematic history: “Fifty Shades of Grey” and “SpongeBob 2.”

Most people will likely watch “Fifty Shades of Grey” in a traditional movie theater and many will watch in their comfort of their own homes on DVD. In Concord, however, it’s playing in the open air – right next to the popular kids’ movie.

The world of Anastasia and Christian collide with Mr. SquarePants just a patch of asphalt away.

While part one of the S&M series can’t be seen from highway 4, it can be seen from across the parking lot where parents taking their kids to see the man who lives in a pineapple under the sea is playing.

“That’s not a good thing. What do the two have in common? And you can see both theaters,” neighbor Joy Peter said.

Not all the neighbors in the Dallas Garden Senior Park, which have a clear view of the drive-in feel the same way.

“It won’t be the first time. I’m sure they’ve had other R-rated movies there on the screens,” said Joanne Gressang.

KPIX contacted the WestWind theaters by phone and email to talk about the combination of movies, but we have yet to receive a response.
