What if time was like a movie at a theater and we were just the projector?

Thinking that time itself was like that actual roll of film, you can hold it in your hands, and what you have is the WHOLE movie AT THE SAME TIME...

...we put ourselves as the projector limiting our view to only one frame at a time in progression.

I think the time projector analogy is perfect. The film is totally linear and we can only experience it as such. If we stop a projector and look at the entire roll of film in our hands it is incomprehensible to our puny brains.

It's not so much that we can't contain all the information in the film (we will eventually see it all and remember most of it). We do not have the capacity to let all of that knowledge into our minds in one instant. The frame by frame passage of time allows us to digest and savor all of time. The experience of now is much fuller than the memory of before. If we devoured all of time in an instant then all would be memory (melancholy forever).

I would stop film and get a refund
If this was true, and you became aware of it, you would become unstuck in time. Then you could jump around and live any part of your life whenever you wanted to.

I believe you would win the favor of the Tralfalmadorian race, who live unstuck in time. (see Vonnegut's Slaughterhouse-five)

This concept is also seen in the Quantum Leap tv series starring Scott Bakula. Your concept sounds very similar to the String Theory on that show. (Not to be confused with the actual String Theory used in physics)
Time cannot be equated to a projector holding an entire film. Time is linear, a single direction - present to past. The physics trilogy describes the basis of our reality, and it gives a clue as to why things operate as they do. The trilogy is: E = mc2, m = E/c2, and c2 = E/m. The last is that of a field of gravity, which is a field of physical time. This equation describes the "c^2" concept as being an energy/mass relationship, while the first two describe the basis of our existence itself is this very same value of "c2".

In the first equation the value of "c2" is the multiplier and in the second the divider. In each of these it is the basis of the equation itself. What this means is that all forms of energy and mass are composed of this value. Our universe and all within are composed of physical time "c2". It is for this reason the present moves into becoming the past at the rate it does, and this rate of change is the same throughout our universe. Every event moves from "present time" to that of the "past", which means our universe moves in a single direction in direction; time-wise. Those who have lived in the past, and who are now dead, yet have their bodies in present time. They have just turned into gasses and dust, but they yet remain in present time. There is no past to return to because it all exists in our very present, just as all those of the future shall be put together by agency of that which exists now.

Were all the mass of our universe converted into electromagnetic energy (of which it is composed), then it would have changed from a three dimensional universe into that of a single dimension. At that instant physical time would have ceased to exist. It requires the presence of a mass to form the concept of time.
Time is not like a movie film, it records events that actors performed in the past, the only reference we have to the past is written records, photos and memories. Limiting yourself to viewing one frame at a time does not require the impossibility of placing yourself inside a projector. Where is the logic in your question?
"IF" in your question gives me courage to answer. Out of mere inquisitiveness, I will be going on "playing" and "rewinding" the movie. Three days before I started the rewinding. Till now it has not reached the beginning. I will invite everybody to view the replay from the "very " beginning.
