Rattlesnake is a 2019 American horror drama mystery film written and directed by Zak Hilditch and starring Carmen Ejogo, Theo Rossi and Emma Greenwell.

Katrina doesn't initially believe it, but when she goes back to the desert road, the trailer has disappeared and she sees a trucker with a missing eye, warning her that Clara is going to die.

After an aborted attempt to kill a dying old man in the hospital, Katrina sets her sights on Billy, an abusive boyfriend she sees criticizing his girlfriend in a bar.

The site's critics' consensus reads: "Carmen Ejogo is stranded in a wasteland both figuratively and literally in this disposable thriller, which lacks the cleverness or specificity to give its thin conceit any bite.

"[2] Writing for The Guardian, Benjamin Lee described the "undeniably talented" Ejogo as "adrift", Hilditch's direction as "bland", and the film overall as "strangely boring".
