Aditya 369 (1991)

This movie begins with a scientist Prof.Ramdas(tinu anand) doing vigorous experiments to invent a time machine.He becomes successful.His daughter hema(played by Mohini) and her fiancée Krishna Kumar(played by balakrishna) accidentally get into the time machine and visit the past(time of krishnadeva raya's empire).This movie has been developed on the lines of "back to the future" movies but is very well made with regards to regionalism.The story revolves around one more important aspect,the diamond in a museum.A person named Raja Verma(Amrish Puri)has a queer hobby of collecting valuables all over the world,makes and attempt to rob the diamond in the present and that is seen by a kid who happens to be there at that time.Science fiction lovers would love this one.The special effects were really good when compared to that time.Screen play and dialouges were crisp and captivating.The actors have given a good performance.Soundtrack given by Mastero Ilayaraja is simply brilliant.Aditya 369 always remains an all time favorite movie for me!
