Tom Hanks takes his soccer seriously. And when the Women's World Cup comes to Canada in 2015, he wants the games played on grass fields.

The actor is adding his voice to those protesting the use of artificial turf for the six Canadian venues. On Friday, Hanks tweeted: "Opinion: Women's World Cup is the best Soccer of the year. Hey FIFA, they deserve real grass. Put in sod."

Forty international players recently wrote to FIFA and the Canadian Soccer Association threatening legal action. They say requiring women to play on artificial turf is discriminatory.

In Toronto this month, FIFA President Sepp Blatter lauded the quality of today's artificial turf. Still, the players in the letter say the risk for injury remains greater than on grass surfaces.

Hanks is a fan of the English Premier League club Aston Villa.
