IMDB( Internet Movie database) is great database for film buffs, mainly for Hollywood, Bollywood and other smaller 'woods' to some extent! (Dunno?... Kollywood= Tamil, Tollywood= Telugu, Sandalwood= Kannada etc)
When you want to recall an old movie, i.e.; when you are on a ‘retro trip’ or want a blast from the past; a visit to IMDB.com is a must.
They have painstakingly recorded Film Industry's products over the decades with credits to the extent available and even allow you (after free registration) to edit the credits, put a synopsis and post reviews with ratings as well. They do not take unnecessarily long to approve your post either.
Before I try to buy up an old Hindi movie I want to see or revisit, or even to try downloading huge MBs of files from free Internet sites, I always visit IMDB first and make sure to know the details of cast, director, Music credits and read a couple of reviews before embarking on catching the actual film... It pays to play safe, you see! And then, you can filter out the riffraff from solid gold!
My own movie reviews ( Hindi and Kannada) (some 30 till now) on this Site are posted here:

Read and comment on my work for sure but more importantly, don't forget, you too can contribute on the site for everyone's benefit.
