Christian Slater Planning July Wedding to Brittany Lopez

"It will be good, intimate and small and family members. It will be nice," Slater told PEOPLE at ABC's New York City upfront on Tuesday.
The Mind Games actor, 43, revealed that he and Lopez are planning a backyard affair for their July nuptials.
"Honestly, you gotta get a planner and do all that, but we will get it organized. We had a big engagement party on the 31st of December and it was nice, it was like a New Year's and we had all the family come, 200 people, so it kind of already feels like we did the wedding, so we are just going to do a nice backyard situation," he said.
But even as the couple closes in on their big day, Slater says there's still plenty to do.
"It's going as smooth as it can go. I mean, right now we're moving into a house. I live in Miami now and, of course, [Mind Games] shoots in Chicago, which is very cold, so now that my blood has appropriately thinned out I'm sure this will run for eight years," he joked. "Yeah, that will be the irony of it all."
Slater was previously married to actress Ryan Haddon and has two children. The couple divorced in 2006.
