'50 Shades' Fan Spots Easter Egg Tribute to Dakota Johnson's Mom

Film buffs have recently noticed a brilliant Easter egg hidden in the second Fifty Shades movie, which pays tribute to Dakota Johnson's mom.

The steamy trilogy was based on books of the same name by E. L. James, with Johnson and Jamie Dornan playing the loved-up main characters, Anastasia Steele and Christian Grey.

Johnson, 31, has acting in her blood, as she's the daughter of Melanie Griffiths and Don Johnson, while her grandmother is Tippi Hedren.

Griffiths, who celebrated her 64th birthday on Monday with a post thanking Johnson and her sister for gifts, is best-known for her starring role in the 1988 film, Working Girl.

Starring alongside Sigourney Weaver and Harrison Ford, she plays secretary Tess McGill, who unofficially promotes herself by pretending she has her boss' job, after her boss breaks her own leg.

The corporate flick set in New York city earned Griffiths an Oscar nod, her only, while the film itself also received a host of nominations, including for best director and best picture.

In the movie, Tess turns to a female colleague, and utters an iconic line, saying: "I expect you to call me Tess. I don't expect you to fetch me coffee unless you're getting some for yourself.... and the rest we'll just make up as we go along, okay?"

Johnson repeats the line nearly word-for-word, only changing the name, in Fifty Shades Darker.

When she too addresses a female colleague, she says: "I expect you to call me Ana. I don't expect you to fetch me coffee unless you're getting some for yourself.... and the rest we'll just make up as we go along, okay?"

The homage was picked up by fan Christasia, who shared side-by-side clips of both films to TikTok on Tuesday.

They captioned it: "Dakota and her mom. This is so cute. Pity her mom won't be able to watch the movie."

They later clarified this was due to the sexual nature of the film, adding: "1. She's alive, in the caption I mean she won't see it because she said it would be strange. 2. The movies are Fifty Shades Darker and Working Girl."

The TikTok clip, which can be seen here, has been seen more than 1.5 million times, as fellow fans admitted they too had never made the connection between the two films before.

"I had no idea that was her mom," Stephwill3 wrote.

Kimmie Cullen admitted: "Mind blown I had no idea they were mother and daughter."

Savann3445 commented: "I love Working Girl, and when I heard Dakota say this line I got so excited."

While Kathy Sexton added: "OK I noticed this only because my mama watched that movie constantly and it finally made sense when I found out they were mother and daughter."

The idea to add in the tribute is attributed to writer Niall Leonard. And it was a hit with Johnson, who told USA Today: "That's my favorite part. I thought it was the sweetest thing ever. Because when has that ever happened in the history of film? And that's also such an iconic line from Working Girl. So it's so special."

Fifty Shades of Grey was released in 2015, followed by Fifty Shades Darker in 2017 and the final instalment, Fifty Shades Freed, was released the year after.

Newsweek reached out to Christasia for comment.
