A crunch game in every Welsh rugby fan's calendar, the Six Nations match against England, is to be the first live 3D sports broadcast in Europe.
Polarised 3D cameras will be at Twickenham for the match on 6 February, with England's clash with Ireland on 27 February also due to feature.
The match will be screened at 40 Odeon and Cineworld cinemas across the UK.
Many believe 2010 is the breakthrough year for 3D technology after the success of films such as Avatar.
At the Consumer Electronics Show, CES, in Las Vegas, last week, all the big name manufacturers unveiled 3D TVs.
The Discovery Channel said that it is forming a joint venture company with Sony and IMAX to deliver 3D TV channels.
UK satellite operator BSkyB said it is also planning to launch a 3D service later this year and ESPN said it will show at least 85 sports events this year on its new ESPN 3D channel.
Backers claim the 3D screenings will give rugby fans the closest experience of the atmosphere inside the stadium.
England's second home game of the tournament, against Ireland on 27 February will also be screened in 3D.
Rugby Football Union operations director Paul Vaughan said: "I hope rugby fans will pack cinemas across the country to support the team and mark this milestone."
Tickets go on sale to general public from 29 January with adult tickets from £12.50.
