I don't know if they really look alike or if it was the haircuts - or the type of characters they usually tend to play (hot, somewhat likeable princesses) - but I thought it was very clever to nab Christina Applegate and Reese Whitherspoon to play Jennifer Aniston's sisters in 'Friends.'
The Addams Family
Zach Braff and Tom Cavanagh on Scrubs.
Sharon Lawrence as Sasha Alexander's mother on "Rizzoli & Isles"
The cast of The Donna Reed Show.
R21 - Peter and Lauren do not look alike. Lauren and Mae Whitman (who plays Lauren's daughter) look alike.
Jon King and J.W. King in "Brothers Should Do It."
Carrington Garland and Marcy Walker on Santa Barbara as Kelly and Eden.
That last one's pretty funny. Perhaps more in the spirit OP intended, how about Elizabeth Montgomery and Erin Murphy on "Bewitched"? They even have the same initials!
Phil and Grant Mitchell on Eastenders.
DJ really looked like he could have been Roseanne and John Goodman's son. The other two looked totally adopted.
From different hemispheres.
And forget about Roseanne's lateral or ascending family. Again, different continents.
Mike Brady and his 3 sons.
The parents/parent equivalents and children in The Donna Reed Show, Father Knows Best, and Family Affair, all looked like they could be related to each other.
i thought jacki weaver and bradley cooper had a similar quality in silver linings playbook. why havent we ever seen helen hunt together with leelee sobieski or uma thurman with sarah polley?
Mary-LouiseParker and the kid who played her one armed son in Fried Green Tomatoes.
Jennifer Garner & Victor Garber
Jensen and Jared, Dean and Sam Winchester.
Robert Downey Jr and Winona Ryder as siblings in 1969
mary mcdonnell as mother of gyllenhaals in 'donnie darko'
Mary-Kate and Ashley Olsen.
Lauren Graham and Alexis Bledel
Charlie Sheen & Emilio Estevez
Barbara O'Neil (Ellen O'Hara) and Ann Rutherford (Carreen) in GONE WITH THE WIND
fairuza balk and ione skye in gas, food, lodging
Teri Garr and Lisa Kudrow
Lauren Graham and a pig would look related but not any of the actresses who have played her daughter
sondra locke and surrogate sister/lover ratboy in ratboy
None of the Cosby kids.
Kim Richards & Ike Eisenmann in those Witch Mountain movies.
precious and that bucket of fried chicken in precious
I always thought young Heather Tom looked like the daughter of Melody Thomas Scott and Eric Braeden.
The Chase family in My So Called Life. Especially the kid who wasn't Claire Danes.
tina yothers and michael j. fox, starr jones reynolds and al reynolds, a piece of shit with eyes and fantasia barrino
Angie Harmon and Jordan Bridges as siblings on Rizzoli and Isles.
Joan Cusack and Ed Begley Jr. were perfectly cast in "The Office" finale as Erin's (Ellie Kemper) birth parents.
I don't think it's necessary to do a spoiler alert on something that has already aired. DVR/Tivo people be damned
On Golden Pond
Jennifer Connelly and Lily Collins as mother/daughter in their new indie movie. Forget its title.
The casts of The Cosby Show and Sister, Sister
What's the movie were Jena Malone played Mary Louise Parker's daughter? Was that "Saved"?
Not a relative but the same person side bar:
I was always amazed at how spot on the actress who played young Dorothy in Golden Girls always was with her posture gestures, voice tone, inflections, and mannerisms.
R67 - Yes. Good casting choice.
[R68} the actress who played young Dorothy was/is Lyn Greene who later became a successful television producer
MLP and Jena Malone did not have the same mannerisms at all in Saved and they look absolutely nothing alike.
Sarah Polley and the CGI monster with the side set eyes that played her daughter in Splice.
Peggy Lipton and Mischa Barton as mother and daughter in Skipped Parts.
Ray Wise and Grace Zabriskie as Sheryl Lee's parents in Twin Peaks/Fire Walk With Me.
David Morse and Rory Culkin as father and son in Down In The Valley.
Lily Tomlin and Lili Taylor as mother and daughter in Short Cuts.
Julianne Moore and Eddie Redmaybe as mother and son in Savage Grace.
When they cast the BRADY BUNCH, the child actors were cast first. Sherwood Schwartz had four sets of child actors cast. One set was blond boys, another set brunet boys, one set blonde girls and the last set brunette girls. Schwartz wanted a brunet father/blonde mother or a blond father/brunette mother combination. One he cast Robert Reed and Joyce Bullifant (who was replaced later by Florence Henderson), Schwartz knew which child actors he was going to use.
Another story; Mary Tyler Moore auditioned for the role of Danny Thomas' daughter on MAKE ROOM FOR DADDY. He told her that with her nose, no one would believe that she was his daughter. He did remember her when it came time to cast the Dick Van Dyke Show.
