It looked like maybe we were gonna miss it all, but then we drove to Buffalo and we got through the border." Actor Daniel Radcliffe on his visa nightmare which almost ruined his Comic-Con debut in San Diego, California. The Brit was promoting new film What If in Canada when he found he was stranded. He eventually made it to the world-famous convention on Friday (25Jul14) and hit the floor disguised as Spider-Man.
