Russell Crowe was in Budapest and people who knew it was through a riddle tweet posted on his twitter with this photo at Károly körút. Everyone knows he is the Gladiator actor, the Oscar-winner. This low profile way of visiting Budapest seems like a secretive one. By the time his riddle could be solved, he had already left and his ending tweet was:
Budapest, what a privilege to spend a day here. Might be the first time I've seen the Danube. Beautiful place so friendly. Bye now.
