Actors Dakota Johnson and Jamie Dornan were both recently spotted in the same Los Angeles airport, sparking speculation that the two have some unfinished "Fifty Shades of Grey" business.

Johnson plays Anastasia Steele in the highly-anticipated movie adaptation of E.L. James' bestselling novel. Typically a blonde, she dyed her hair brown in order to fit the part. After shooting the film, Johnson went back her original blonde tresses, Express reports.

On Sunday, however, the 24-year-old actress was seen landing at LAX with her Anastasia Steele brown hair once again. According to Express, Johnson was meeting up with Sam Taylor-Johnson, "Fifty Shades of Grey" director.

Dornan, who plays S&M-loving billionaire Christian Grey in the film, was also spotted at LAX "at around the same time," Express reports.

Because of Johnson's return to her "Fifty Shades of Grey" look and her being in the same airport as her co-star, some sources, such as The Stir, have speculated that the two are re-shooting films due to poor chemistry, or are handling other movie related business.

Neither Johnson nor Dornan have commented on the reports.

Meanwhile, Dornan recently opened up about another career changing role for him: that of serial killer Paul Spector in BBC2's "The Fall."

According to the 32-year-old actor, the dark role definitely has had an effect on him.

"You can't fail to be left slightly scarred by inhabiting someone like that for two seasons," Dornan told Daily Mail. "I do carry elements of him with me in a worrying way. I find him relatable ... I have a deep understanding of him and why he is why he is."

"The Fall" has been called "the most repulsive drama ever broadcast on British TV." Its second season was launched on Tuesday.

"He had such distaste for everything," Dornan continued. "You do carry some of that anger and that hatred in you a little bit, especially towards the end of a few months playing him."

"Fifty Shades of Grey" hits theaters Feb. 13, 2015.
