I have had this doubt since i saw the film Jurassic Park.In that film the little boy is thrown off from a HVDC line.Whereas in the case of Low voltage AC people are struck to the line.Does the picture signify the truth.If yes what is the possible reason?

No there's nothing like that.You get thrown because of abnormal contraction of muscles.Electricity is not throwing you.Both are dangerous and damage is determined by amount of time you are in contact, strength of current and power loss that takes place in your body.Reason DC is used has to do with cutting transmission losses.If you have to fence very large area and you want to keep power losses to minimum you use DC.
Therefore whether you get stuck or not has to do with the way your muscles react to this stimulus and not on AC or DC.

Without really knowing what sort of electricity used in the film "Jurassic
Park", I would suspect that the "High Voltage" used is actually quite similiar to the ones use in a cattle fence, a "High Voltage Pulsed DC". If it is a continuous High Voltage (AC or DC), that poor person would have been toasted.
"Low Voltage AC (220/110V)" is also lethal, just that being "stuck" to the line is cause by muscle spasm from the electrical charge. In either case, death will occur soon enough if a person is left "stuck" to the line.

Well, if you ever touch a low voltage AC line, you may live to tell the tale. If you touch a high voltage AC line, your dead. The same goes for DC voltage.
It matters not whether the current flow reverses, or the voltage becomes negative or not. If your body is exposed to an intense amount of electricity in a short amount of time, your cooked. AC voltage usually have a high frequency, so that even though there is a slight moment when no voltage is present, it would've gone pass you before you even realise it.
No matter which voltage you encounter, you will stick to it unless you have enough force inside you to counteract the electromagnetic force (?) or the attraction from the electricity. Low voltage, even from a normal power plug (240V RMS) gives the person enough chance to move if touched only slightly. High voltage (i.e. 10000V) will fry you without giving you any hope of pushing free.

Voltage is the Cause, Current is the Effect. Voltage, V : Voltage is a potential difference between two points. Current, I : Current is the rate of flow of charge.

Low voltage takes more time to kill than a highvoltage when one touches them.
In a film a hero will never die whaterver is the voltage. He has to act in the next film.

AC or alternating current fluctuates so you have a chance to let go. HVDC stays on so you can't let go, and if the current is high enough you die. It only takes 10 milliamps through your heart to kill you; as demonstrated on the MYTHBUSTERS. I have touched a plug as it was plugged in to a 120 AC line with a 20 amp potential. I jumped and let go, with no harm.

The voltages you mentioned are deadly to any person. If you are grounded well you most likely will be killed. It is how well you are grounded that makes the real difference.
