Judge approves subpoena for "Rust" assistant director who declined several interviews

The assistant director who handed Alec Baldwin a prop gun that killed a cinematographer on a New Mexico film set must make himself available for an interview with state workplace safety regulators, a judge has decided.

District Judge Bryan Biedscheid on Friday granted a request by the Occupational Health and Safety Bureau of the state Environment Department to issue a subpoena to Dave Halls, assistant director for the movie "Rust," local news outlets reported.

Cinematographer Halyna Hutchins was killed and director Joel Souza was wounded in the October 21 shooting on the Bonanza Creek Ranch film set near Santa Fe.
