The "Avengers: Age of Ultron" director described the new footage - featuring Chris Pratt and Bryce Dallas Howard - as "'70s era sexist", reported Collider.
The scene sees Pratt's dinosaur-keeper Owen Grady chat and flirt with Howard's uptight operations manager Claire Dearing.
Responding to a post referencing Chris Pratt's looks in the preview, Whedon wrote: "I'm too busy wishing this clip wasn't '70s era sexist. She's a stiff, he's a life-force - really? Still?"
"Jurassic World" director Colin Trevorrow has yet to respond to Whedon's comments.
The fourth instalment of the "Jurassic" series will be released over a decade after "Jurassic Park III", as the Masrani Global Corporation seeks to open a brand new theme park.
