I haven't seen the film, but if physicalism is true then of course consciousness can't be "transferred" since consciousness is a physical phenomenon; to "transfer" it would merely be to move it to another spatiotemporal location. If physicalism isn't true then we still couldn't transfer consciousness because even if the physical has causal efficacy over the phenomenal, it would again just involve spatiotemporal relocation. Really the whole concept of consciousness transfer is, in my opinion, confused, and is due to a misconception of personal identity. Consciousness cannot be transplanted from one physical system to another because consciousness is what it's like to be a particular physical system.
Personally I'm skeptical of serial computationalism and think it will require breakthroughs in quantum computing to be able to develop conscious robots (due to the combination problem/binding problem).
