The actress plays the lead role in her director spouse Paul W. S. Anderson`s `Resident Evil` franchise and believes being on set together keeps their relationship fresh.
She said: "Paul is so into it. He loves what he`s doing. You`ll do something and you`ll hear from the monitors, `Yeah!`.
"When we`re on the film, that`s all we talk about, how to make it better. We have a very creative relationship. It`s a lot of fun because what`s a relationship if all you`re doing is cooking and going to the movies every Friday night? We`re having something that is symbiotic - it`s like a continuous card game between us."
Milla has just completed work on the fourth movie, `Resident Evil: Afterlife` and can see herself returning to the franchise for more films.
She added to Total Film magazine: "As long as people still want to see them, I think I still have a couple of years in me. And as long as I still look good. It`s exhausting on a physical level, generally but it`s just really nice to have this kind of film to fall back on.
"I do a lot of films that are very dark and intense emotionally. If I did things like that all the time I would kill myself."
