There are many beautiful and cherished reasons to work with your husband. I just can't think of them right now. My husband and I are both filmmakers and recently shot our first feature The Tested together. Before we started shooting, we sat down and put a list together of rules we had to abide by, the first being no calling each other "baby" on set. Figured it might not go over very well with the crew.
Working with your spouse can be difficult because of the comfort level. It's easy to fall into husband and wife world but it's more difficult to try to maintain the respect and atmosphere that you'd have with someone you didn't share a bed with.
It's so important to treat your significant other as you would anyone else. You have to carve out the time to speak about your business and brainstorm about new ideas, because if you don't set aside the time, it's easy to ignore each other and play angry birds while watching Celebrity Apprentice (yes, we watch it and we are unapologetic).
The truth is we work well together, he's the quiet, creative force and I'm the mouthpiece. We have a short hand, and if he sees me on set, he knows there's a problem.
I recently directed my first short The Busker, and he was the DP. I couldn't have done it without him. He was my safety net and helped me through the whole thing. I could have done without him yelling "cut" those few times, but I can't blame him for falling into old habits.
I wouldn't trade working with my husband for anything. The lows are low and there are many but the highs are higher because you share them.
He inspires me more than anyone I know and I feel lucky to be his wife and business partner. In that order.
