The cinema routinely violates physics principles for dramatic effect, 
but yes, they have "done it" with dead people on Star Trek.

Yes, and as the video indicated, it takes more energy to decelerate to 
a sufficiently slow orbital velocity to "hit" the sun than it takes to 
actually escape the solar system in total.
