Here's my list of [url]BIG BUDGET BOMB'S[/url]:
1) Premji's Imman Dharam,combined talents of Sanjeev Kumar,Helen
Shashi Kapoor,Amitabh,Rekha & Salim-Javed couldn't save this turkey. Original 180 minutes original version was trimmed to 150 but turkey is a turkey.
2) Raj Kapoor's Mera Naam Joker, One of all time big bomb's.
3) Mehboob's Son Of India was a nail in his coffin.
4) Ramanand Sagar's Lalkar with Mala Sinha,Dharmendra,Rajendra Kumar,failed attempt to bring WWII drama to Bollywood, from start to finish it really sucked. On the DVD jewel box it's listed as being a big hit, all lies, it's really bad.
5) Manoj Kumar's Clerk, by this time he was drained of all creative juices.
6) B.R.Chopra's Dastaan with Dilip Kumar & Sharmila, a milestone in bad film making.
7) Joy Mukerjee's Humsaya with Mala Sinha & Sharmila, it's reported to be one of the costliest movie made during 1967-68 period but nothing could save this disaster, now remembered for classic O.P.Nayyar tunes, a great preformace by Mala, those infamous catfights between Mala & Sharmila and forced Joy to sell everything and one time A list star was reduced to doing D grade movies.

H.S.Rawail's Sunghursh with Dilip Kumar,Vyjanthimala & Sanjvee, after this bomb in 1968 Rawal next hit was not until 1976's Laila Majnu.
9) Dilip Kumar's Dil Diya Dard Liya with Waheeda & Pran, this take on Whuthering Heights was given a big thumps down was moviegoers.
10) O.P.Ralhan's Hulchul with Zeenat,Kabir,Helen & his following disaters Paapi with Sunil Dutt,Reena Roy,Sanjeev & Zeenat and Bandhe Haath with Amitabh & Mumtaz finally send Ralhan packing.
11) Anything by Devanand list is too long Heera Panna, Prem Pujari, Loot Maar, Ishq Ishq Ishq, Return of Jewel thieg and on and on.
12) Silsila with Amitabh,Jaya,Sanjeev & Rekha, great talent couldn't fool moviegoer's.
13) Sacchai with Shammi Kapoor,Sadhana,Sanjeev,Helen,Pran this one's budget from South India could have produced 2-3 movies, really really bad it's reported the producers spent at 10% of movie's budget on a really bad dance sequence with Shammi & Helen.
I'm gonna stop now.
*Just a note, The film maker's of all these bombs thought they were making great ground breaking films but it boy they were so wrong.
