The document provides three potential thriller film ideas and discusses some potential problems or challenges with filming each idea. Idea One involves two girls drugged in a deserted field who are stalked by a killer. Filming in a field poses equipment access and camera angle challenges. Idea Two involves teenagers camping near a lake where a girl is stalked after seeing a mysterious figure. Finding a suitable filming location near a lake and achieving the desired editing may be difficult. Idea Three involves a girl having a psychotic episode while on a beach, train station, and in a city. Transportation of equipment to varied locations like a beach, finding an abandoned train station, and filming in a city present logistical issues.
