Zelda Williams, the 20-year-old daughter of comedy icon Robin Williams, is set to headline Mind Blur Productions’ fact-based murder-spree thriller Powder Burns.

The Mind Blur press release reads:

Ms. Williams will play Emily Tomassini, an intelligent and devoutly religious but headstrong young woman who has been battling her mother and father over her relationship with an older, married health care professional named Philip Newman.

After Emily’s spiteful dad, Paul Tomassini, has a violent confrontation with his daughter’s lover, the battles escalate into an all-out war that culminates in Emily and Philip going on a blood-soaked rampage in Emily’s childhood home that leaves four people senselessly slaughtered, including Emily’s parents and younger brother.

I had no idea that Robin Williams (One Hour Photo, Insomnia) had a daughter. I’m happy to see that she’s no where near as hairy as him … well, at least, not in the noticeable areas.

Powder Burns will begin shooting in April.
