Directed by Govind Nihalani, this is definite cop film of Indian cinema. May be the first one which portrayed the stark reality of corruption in the police force & politics with no holds barred & how it effects on a young cop. A man forced to join a career of a cop by his cop father. Agreed that we grew up watching lot of good cop/bad cop Hindi films but this is different. Today's generation, which grown up watching dark & realistic films like- 'Satya', 'Company' may be consider it inferior product in comparison but look at the time of its making. The film was made absolutely off beat tone in the time when people didn't pay much attention to such kind of cinema & yet it becomes a most sought after cop film in class & mass audience when it released. For Om Puri its first breakthrough in mainstream Hindi cinema & he delivered a class performance as Inspector Velankar. Its more than cop character, he internalized a lot which is something original in acting. Watch his scenes with his father whom he hates & Smita whom he loves. Smita Patil maintained the dignity of her character to the expected level. My God what a natural expressions she carried!!! Shafi Inamdar was truly a discovery for me & he's a brilliant character actor if given a chance & here in some of the scenes he outsmarted even Om. The movie is also a debut of a promising villain on Indian screen- Sadashiv Amrapurkar as 'Rama Shetty'. It's another story that he didn't get such a meaty role & almost forgotten today as one of the loud villain of Dharmendra's B grade action films. Watch the scene where Om 1st time becomes a rebel for his father (played by Amrish Puri) & next both are sharing wine together. How inner truth started revealing for both the character with confronting feelings of love & hate for each other. Two faces of Indian Police Force- Masculinity & Impotency and in between lies- half truth (ardh satya)Kudos to Nihalani's touch. The film won 2 National Awards as Best Hindi Feature Film & Best Actor- Om Puri & 3 Filmfare Awards in Best Film, Best Director & Best Supporting Actor Categories.
Recommended to all who are interested in nostalgia of serious Hindi films.
Ratings- 8/10

In a way, Corridors of Time is a success story because the movie reaches its goal : being seen by thousands. But it fails at making them laugh...
Les Visiteurs has had its success, because the subject was an original way of considering the time travel : forget about Zemeckis's Back to the future, here comes the old France, the middle-age knight and its nearly barbaric way of life. Full of pride, funny thanks to the ancient words he uses, Montmirail can sometimes be disgusting but he keeps his honor. Then comes the sequel.
Nobody had foreseen the tremendous success of Les Visiteurs, the first. And it's no use being a movie expert to realize that the Corridors of Time has been made for money.
The general story begins after the end of Les Visiteurs, and immediately tries to justify the sequel with a time paradox that would have needed some second tought. Explanation : it's no use trying to get back the jewelry Jacquouille has stolen ; don't you remember this nice red shiny and expensive car he bought at the end of the 1st episode ? Where do you think he found the money ? Selling the jewelry... And that's only one of many holes Poiré tries to avoid... and fails.
Let's have a look at the characters : Montmirail doesn't change, he's just a little more boring. Regarding Frenegonde... that's another story : Valérie Lemercier decided not to compromise herself in this sequel to avoid getting stuck in the bourgeoise role. And Muriel Robin tries to imitate her in a way that I found so pitiful I nearly felt pain for her. And Poiré doesn't realize that a cast of humorists isn't enough to make a good comedy.
Forget about the time travels, about the digital effects, concentrate on the story and you'll see that there's enough room on a mail stamp to write it 10 times.
The main interest of this film is the landscapes. A movie for youngsters, let's say up to 13 years old.
