How can I create really high detailed models in short time

[pcf43]

Ok so basically what I am looking for is a way or modelling tehnique to make nice high poly models(an example of what kind of quality I want is the Hope trailer from Star Wars The Old Republic, and the new Force Unleashed 2 e3 trailer so basically cinamatic trailers graphics) in a short time(2 weeks mostly/model or so) Also how can I create high quality physics without any engine?

Now I now many of you will say try plane modelling, the thing is I don't understand how to use it i mean yeah, you place refrence planes and start modelling by extruding edges from a plane making this way rows of planes are made and then you loop them or ring(by case) to create other rows and so on, but i never understood how many faces a high poly model needs to have, also i got the feeling i do not no how to use the entire tehnique correctly.

If anyone can link me some good high poly modelling tutorials, or tell here in short how you do it I would be really, really greatfull, also, does high poly modelling really takes so long to make?
