Asked if he was teasing taking over the role from Craig with the selfie, Elba said: “Nah, we just did it on the spur of the moment, thought it would be a laugh.
“It was a selfie. Didn’t realise it would be picture of the year.”
Meanwhile, Elba has revealed why he doesn’t think he would be right for Bond.
Speaking with Event magazine, he said: “Bond is one of the biggest franchises in the world, and for that reason, whoever ends up playing it, lives it.”
He added: “You’re THAT character, and known as that character for many, many years.
“I’m creating characters now that can still live alongside Idris.
“Not ones that take over me and solely define me.”
Daniel Craig stars in Bond 25, which is set for release in UK cinemas on April 3, 2020.
