Great Britain's Andy Murray has described the atmosphere inside Centre Court this afternoon as "weird".
The third seed for the men's singles got his bid for a gold medal off to the best possible start by overcoming Switzerland's Stanislas Wawrinka.
Speaking afterwards, the world number four said: "It's a slightly different crowd to Wimbledon.
"It's just weird - there are so many colours, there is a lot of noise with the music and stuff when you come out that you don't get at Wimbledon, which is slightly different. The support was great."
The 25-year-old will take on either Finland's Jarkko Nieminen or Somdev Devvarman of India in the second round.
