Playwright Matt Williams created the TV series Roseanne, co-created the TV series Home Improvement, and was a writer on The Cosby Show, which is to say that the man knows a little something about domestic comedies in which hard-working parents love and nurture their large families. In his new play, Actually, We’re F**ked, he attempts to go in a different direction, exploring whether two young couples who are barely holding their marriages together can stop fretting, navel-gazing, and betraying each other long enough to have, or even want, a ch**d.
