The character appeared in a Mr Bean-esque role, playing the keyboard and starring in a pre-recorded video homage to Chariots of Fire.
Writing on the official Twitter blog, Andrew Fitzgerald, manager of editorial programming, said: "The biggest spike in Twitter conversation during the Opening Ceremony?
"When Rowan Atkinson, aka Mr Bean, appeared in a hilariously memorable homage to the Olympians of Chariots of Fire."
He added: "Only the world's best athletes get to experience the thrill and privilege of marching in the Parade of Nations at the opening ceremonies.
"And as they tweeted pictures during every step of their memorable night, they took all of us along with them."
He then posted several photos from Olympic athletes and an image of Paul McCartney just before he took to the stage to perform The Beatles' 'Hey Jude'.
