Gellar rules out Prinze pairing
The husband-wife team have co-starred in five films to date.
But TV's Buffy has found combining home and work lives too difficult.
She said: "It's difficult to live with someone and come to work too. I wouldn't recommend it. Luckily in this situation, we were doing a big action, fun, cartoon movie.
"It wasn't serious and I didn't go home every night wondering, 'How ever will I say my one line tomorrow?'
"It was a little bit easier and freer, but I don't think you'll ever be seeing the big drama story between us."
The couple have so far worked together in "I Know What you did Last Summer", "She's All That", "Scooby Doo" (one and two) , and lent their voices to the animated "Happily N'Ever After".
