Where to begin with that question:
how about Harrison Ford ?
He used to be married to a writer (film scripts), and together they had a number of children. I remember him complaining that the kids would not sleep in their own beds at night because they kept coming into their parents' bedroom and piling into bed with the grown-ups.

Next thing you know, the marriage has ended in divorce, and he is seeing a very slender young actress named Calista Flockhart. Eventually the two of them get married, and are married today.

Now, Calista Flockhart's claim to fame, before this, was playing the lead role in a television 'dramedy' titled Ally McBeal which aired from 1997 to 2002 on the Fox network. The creator of that somewhat notorious series is named:
David E. Kelley.   According to his Wikipedia article,
"Kelley is one of a very few screenwriters to have created shows that have aired on all four top commercial U.S. television networks."

Before Ally McBeal, Kelley worked with Steven Bochco on such television series as L. A. Law and Doogie Howser M. D.

And he wrote and produced the feature film Lake Placid, in which Brendan Gleeson plays the sheriff who blows up a giant crocodile with a grenade launcher, while a second crocodile is tranquilized and loaded on a flatbed truck, and Betty White is seen feeding the crocodile babies at the end of the film.
