No can do with Earth, but here's one from the moon.
OK I'll go slow.....
It's possible on earth but not necessary since re-entry and landing can be achieved by utilizing the atmosphere (un-powered glide and/or parachute decent).
There has never been any reason to build and operate a retro rocket earth landing vehicle, therefore one has never been built, and hence never been filmed.
1)The engine would have had to have been 600% more powerful than the decent engine on the LEM
2) The structure of the vehicle would have had to have been 600% stronger

Did you know that you can run the same apollo guidance software used in the real missions by emulating the apollo guidance computer and that in physical simulations of the apollo mission the thing really works at navigating to and landing on the moon? NASA had previously successfully soft landed the surveyors, there's no reason at all to believe they couldn't do the same thing with a manned craft.

After Stafford's camera failed, he and Cernan had little to do except look at the scenery until time to dump the descent stage. Stafford had the vehicle in the right attitude 10 minutes early. Cernan asked, "You ready?" Then he suddenly exclaimed, "Son of a bitch!" Snoopy seemed to be throwing a fit, lurching wildly about. He later said it was like flying an Immelmann turn in an aircraft, a combination of pitch and yaw. Stafford yelled that they were in gimbal lock - that the engine had swiveled over to a stop and stuck - and they almost were. He called out for Cernan to thrust forward. Stafford then hit the switch to get rid of the descent stage and realized they were 30 degrees off from their previous attitude. The lunar module continued its crazy gyrations across the lunar sky, and a warning light indicated that the inertial measuring unit really was about to reach its limits and go into gimbal lock. Stafford then took over in manual control, made a big pitch maneuver, and started working the attitude control switches.Snoopy finally calmed down..
*sigh*

Elevators and rudders only apply to atmospheric flight (and in fact, rudders don't do anything to pitch). Do you udnerstand what a gimbal is at all?

Yes, it is easy to land going backwards
