Wouldn't the film have to be processed before it could even be seen properly? How did, for example NASA, shoot film on the moon, process the film, and transmit it live to televisions all across the US?
You're mixing up film and video, two different technologies for recording (and, in the case of video, also transmitting) a moving image. Film is photochemical, and has been around since the 1890s; video is electronic, and has been around since the 1930s. Digital TV broadcasts are a much later innovation. If the 93 in your username is a birth year, then you grew up without them.
Though it required elaborately customized equipment, the moon landing you cite as an example was broadcast just like anything else: a video camera that sent a signal out through an antenna.
For Apollo 11, the feed went from the moon to a large dish in Australia, where it broadcast to a special monitor with a second camera pointed at it to broadcast to the whole world. Kind of complicated, but the only way they could figure it out at the time due to differences in video format between the mission camera and commercial TV.
