“Lonestar” actress Eloise Mumford is the first to be cast in Paranormal Activity director/producer Oren Peli’s ABC pilot “The River.” Mumford will play a helicopter pilot searching for a missing Reality TV explorer and his camera man—her father—along the Amazon river.

Peli is producing the shaky-cam (surprise!) horror series with partners Jason Blum and Steven Schneider. Jaume Collet-Serra (Orphan, Unknown) will helm the pilot episode from a script by Peli, Michael Perry (Paranormal Activity 2), and veteran scribe Michael Green (“Heroes”), who was brought in to rewrite the original draft.

Mumford made her acting debut on the Starz drama series “Crash” in 2008. The 24-year-old last starred on the short-lived (canceled after two episodes) Fox show “Lonestar,” where she played the gullible girlfriend of a Texas conman. She and British actress Imogen Poots have the unfortunate distinction of being cute chicks with horrendous, old lady names.
