On Tuesday, a platform collapsed during filming of the latest sequel, "Resident Evil: Retribution."
Jovovich tweeted that 15 of the injured actors were able to return to work shortly after receiving medical attention.
She said one woman remained in the hospital and could be there for weeks.
Jovovich visited the actress, an extra whose name is Akiko, and then posted, "Thank god she's moving her hands and feet and not in critical condition. I can't believe she said she wants to come back and finish her part, she's incredible."
Jovovich also said that because the injured actors were dressed as blood-covered zombies when the platform collapsed, it was tough for paramedics to determine who was hurt and who was just in makeup.
