Already one of the most talked about films of the year, Oppenheimer continued its European press tour last night, hosting a photocall in London's Trafalgar Square.
On the same evening, less than a mile away, Margot Robbie and the Barbie cast turned the London Eye pink following its European premiere in Leicester Square.
The two films have been merged together by fans and marketing masters to create Barbenheimer - a celebration of two incredibly different films, each set to drop on July 21, offering fans a chance to enjoy a double-feature brimming with Irish talent.
While Galway woman Nicola Coughlan dazzled on the pink carpet for Barbie, Cork man Cillian Murphy looked as dapper as ever on the black carpet for Oppenheimer.
Murphy, who stars as American theoretical physicist J. Robert Oppenheimer, attended the event alongside castmates Robert Downey Jr., Christopher Nolan, Emily Blunt, Florence Pugh, and Matt Damon.
While Murphy kept things casual in a black cardigan worn over a simple white t-shirt and black trousers, British actress Florence Pugh wore a blue denim dress from M05CH1N0's Jeans collection, and Emily Blunt shone in a copper suit from Dolce and Gabbana.
Elsewhere on the red carpet, Robert Downey Jr wore a powder blue suit with white and aqua blue runners, while Matt Damon kept things simple with a smart shirt and trousers.
