Plans reveal Prince George is to join Duke and Duchess of Cambridge's New Zealand and Australia Royal visit.
The Duke and Duchess of Cambridge wore 3D glasses as they watched the latest film by naturalist and broadcaster Sir David Attenborough.
Prince William has stepped into the row over racism in football, saying there is "sadly more work to do" to eradicate it from the game.
The Duke of Cambridge said tonight there is "sadly more work to do" to stop racism in football.
Speaking at a gala dinner to mark the 150th anniversary of the Football Association, Prince William praised the organisations attempting to remove discrimination from the game.
"I am proud of the work of Kick it Out, which is also celebrating an anniversary - its 20th - this year," said the royal, who is also the president of the association.
"There is sadly more work to do, but it is heartening to see how seriously the FA takes stamping the blight of racism and discrimination out of football."
His comments came after Manchester City's Yaya Toure complained of fans making monkey noises during his team's midweek Champions League victory over CSKA Moscow in Russia.
The Duke of Cambridge said he hoped to encourage his favourite football club to "new glory", at the 150th anniversary celebration gala of the Football Association.
Prince William joked that sadly the Queen, who is patron of the FA, has only enjoyed "one occasion when Aston Villa topped the league".
Prince William's ambition to persuade his son George to follow Aston Villa could see the future King join a powerful set of supporters of the Midlands team.
Today marks 150 years since the Founding Fathers of football met to form the Football Association (FA) and create the laws of football.
The FA will host a gala dinner in London this evening to celebrate and will be joined by the Duke of Cambridge and footballing legends from around the world.
In the video address, Prince William, who is President of the FA, added that he is looking forward to watching the team he supports, Aston Villa, with his son George in the future.
Prince George will be christened during a ceremony that will be both a private family occasion and a historic event.
The Duke and Duchess of Cambridge's baby will be welcomed into the Christian faith surrounded by his immediate family and the close friends of his parents.
But as a future King, his baptism in the little known Chapel Royal at St James's Palace on Wednesday afternoon will be performed by the Archbishop of Canterbury, the Most Reverend Justin Welby.
The guest list has not been released but Kensington Palace has said that "close members of both families" will attend including the Queen, the Duke of Edinburgh, along with the Prince of Wales, the Duchess of Cornwall and Prince Harry.
Two guard dogs used to protect the Duke of Cambridge have been put down within days of him leaving his military base.
Bruce, a Belgian Shepherd, and Blade, a German Shepherd, were euthanised after the prince completed his final shift as a search and rescue pilot at RAF Valley on Anglesey, The Sun reported.
The Ministry of Defence confirmed the dogs had been put down, but described the timing as "a coincidence".
A spokesman said: "It is true two dogs have been put down, a couple of days after (Prince William left RAF Valley earlier this month)."
Bruce, who was aged nine, had "come to the end of his working life", while Blade "had a record of veterinary and behavioural issues" which meant the dog could not be reassigned to other duties, the spokesman said.
