The Desperado star helped raise Johnson from a young age after marrying her mother Melanie Griffith following the actress' divorce from Miami Vice star Don Johnson.

The young actress plays a naive student who is seduced by a bondage-loving businessman in the big screen adaptation of E. L. James' novel, but Banderas has ruled out ever watching the movie because it would be too awkward seeing Johnson in sex scenes.

He tells U.K. TV show Loose Women, "No (I won't watch it). I met Dakota when she was four years old, I almost changed her nappies. It's very weird to go and see that movie! I won't be stopping some day (to watch it) on television - I will pass it (change channels)."
