Some of the ones I remember, just because I’m old and involve some of my favorite movies.
Lionel Barrymore (Mr. Potter from It’s a Wonderful Life) is Drew Barrymore’s Great Uncle.
Debbie Reynolds (Singin’ in the Rain, God I love that movie) was Carrie Fisher’s mom.
I think everyone knows Dakota Johnson’s parents, Don Johnson and Melanie Griffith.
Shirley Maclaine (The Apartment and Two Mules for Sister Sara) is Warren Beatty’s sister.
And some cool but not duo-celebrity relative facts.
Ewan McGregor’s brother was a pilot in the RAF and his call sign was Obi-Two.
The awesome Bogart movie, To Have and Have Not (“Put your lips together and blow”) was written by Hemingway and adapted into a screenplay by William Faulkner. Both considered in the top five of all time American authors. (Unless you think Steinbeck was better, then 6th (Which I don’t)). Faulkner and Hemingway were not particularly fond of each other, but then I don’t think there was a lot of love lost between Hemingway and his contemporaries.
These are great!
Angelina Jolie’s father is Jon Voight
Arnold Schwarzeneggers son in law is Chris Pratt.
Ha ha no way. Really?
Chris Pratt is married to Kathrine Eunice Schwarzenegger, who is the daughter of Arnold and Maria (Shriver). He has 3 children with her, all of which have John F Kennedy as a Great Uncle.
Diane Ladd is Laura Dern’s mother…and in Wild at Heart they play as mother/daughter.
Also, (way more obvious) Bruce Dern is Laura Dern’s father irl
Jonathan Nolan is Christopher Nolan’s nephew and they share an uncle in John Nolan.
Jonathan is actually Christopher Nolan’s brother
Ah then that’s why John is an uncle to both of them. I must have misremembered.
I always remember because Jonathan has an American accent and Christopher has a British one which I always found super interesting for some reason, due to where they were each primarily raised/attended school
