Have brother and sister, Julia Roberts and Eric Roberts, ever been in a movie together?

Only once.

The action western Blood Red (1989), which took three years to release and is now solely remembered for being the only film Eric and superstar sister Julia Roberts appeared in together

PS. All sources state that they have reconciled since 2004

He confirmed that he and his more famous sister Julia Roberts were estranged for several years. The source of the estrangment had been Eric's past drug abuse, and Julia's siding with his ex-girlfriend over the custody battle over Emma Roberts. In 2004, he told People magazine, that he and Julia reconciled when he went to visit her in the hospital after she gave birth to twins
