This movie started one hour back and it will remain on for two more hours.



Please check my sentence.

I'd say 'This movie started an hour ago and it still has two hours to run'.

I've deleted your second question. You've been asked to post only one question at a time.

I'd use Rover's version and possibly change the last word to "go".

 

[Rover_KE]

I considered that, but decided that 'to go' and the earlier 'ago' sounded too much like repetition - which we're always telling tufguy to avoid.

 

[emsr2d2]

That could be avoided with "The film's been on for an hour and it's still got two to go".

 

[Charlie Bernstein]

This movie started an hour ago, and it will go two more hours.

Checked! I think "ago" is the best choice.

 

[probus]

Given that you don't want to use the Indian dialect you must say "ago" rather than "back".
