Well my problem remains… If they were not using the kiss scene in the movie why did they even care filming a second one? I always thought « when he grabs her ass and lifts her with his tongue in her mouth » was the first shot of two, correct?

There’s actually probably many of them. We only saw two of them really kissing. One is the deleted scene, the other one is in the bloopers, and god knows how many of them remain unreleased. We don’t know which one they filmed first, it’s probably none of them. No one knows what happened in their mind for those unscripted kisses except that they were “just goofing around.”
