(Reuters) - Andy Murray's second-round win at Wimbledon over Germany's Tobias Kamke was so routine that the British number one was barely quizzed about the match on Wednesday.

Instead, the Scot was grilled about what film he had watched on Tuesday (Scream), what movie he plans to watch before his next match (Scream II and Scream III) and what he thinks about the row erupting erupted over a united British soccer team at the London 2012 Olympics.

"I don't want to get into any of that political stuff. I've been involved in the Olympics, played under Great Britain, and it was an unbelievable experience," fourth seed Murray told reporters after his 6���3 6���3 7���5 win.

"I loved it. It's not for me to decide. It's up to the federations, that they can decide.

"Certainly not getting drawn into any political stuff around this time of year, because we know what happens with that," grinned Murray, who once got into hot water after proclaiming he always backed the team facing England in a football match.

The British Olympic Association angered Northern Ireland, Scotland and Wales by trumpeting a 'historic agreement' for Britain to field a united team at the London Games after a 52-year absence.

The three associations oppose the idea of their players joining any Team GB as they fear their independent status on the world soccer map could be jeopardized.

As far as tennis is concerned, Murray has pretty much represented, and carried the hopes, of Team GB on his own shoulders for almost six years and he is once again mentally prepared for Murray-mania to engulf the tournament.

However, before his fans get carried away with hopes that the 24-year-old could end Britain's 75-year wait for a British men's champion, he warned of a potential horror show when he faces big-serving Croatian Ivan Ljubicic in round three.

"The matches are going to get very tough," said Murray.

"I play Ljubicic now. I've lost to him a few times. A tough player. So I expect that to be a difficult match.

"He serves well. That always makes it difficult. His best results are on grass, which is surprising for someone that serves like him. So that obviously makes it tricky."
