Can you imagine a real-life Twilight Sparkle from “My Little Pony” stabbing someone in the chest and ripping out the victim’s intestines with their horn? If you can’t, Alex Scharfman’s new horror-comedy film “Death of a Unicorn” is sure to paint the picture delightfully dark red. Loosely based on the real “Unicorn Tapestries” — famous textile Dutch depictions of unicorns from the late 13th century — “Death of a Unicorn” shows the mythical creatures as eloquently violent and vengeful. But not without a cause.  The plot kicks off with Elliot, played by Paul Rudd, and his daughter Ridley, played by Jenna Ortega, running over a unicorn on their way to a mansion owned by Elliot’s rich boss — Odell Leopold played by Richard E.
