Before they were Real Housewives, Kyle and Kim Richards were child stars.

Kyle – freshly reconciled with her sister after their fallout from Kim’s alcoholism – reminisced about Hollywood past for #ThrowbackThursday, sharing a photo of the girls on set with James Brolin for the 1977 horror movie The Car.

“Me stuck in the middle of #jamesbrolin & @kimrichards11 filming the movie The Car …. I did not appreciate how cute my movie ‘Dad’ was,” Kyle, 46, captioned her Instagram.

Kim, 51, accepted a plea deal for her April public intoxication arrest last week but still faces charges after allegedly trying to shoplift hundreds of dollars worth of items from Target in August.

She and Kyle feuded through most of The Real Housewives of Beverly Hills‘ latest season but seem to be on good terms now after celebrating Kim’s birthday together. (Kim will not appear as a regular when the reality show returns.)

In June, Kyle announced that she’s producing a comedy based on her, Kim and sister Kathy Hilton growing up in show business.
