Bollywood movies sometimes turn into a series of films releasing over the years getting bigger and better with time. These sequels sometimes turn out to be great success, or prove to be an utter disaster. Let’s take a look at some of the upcoming sequel films, that we think you should watch out for. Who knows, maybe they’ll be much better than their prequels. Take a look:Dabangg 3: Salman Khan will once again be entertaining everyone as the most loved character inspector Chulbul Pandey in the Dabangg 3. The film is apparently going to be a prequel showing us the story before Dabangg and Dabangg 2. Actress Sonakshi Sinha will once be joining the star as Rajjo Pandey. All the more reason to wait for Eid 2017!Don 3: Bollywood’s King Khan, Shah Rukh Khan’s Don 3 has been making a buzz even already even though the film is still only being casted. After the first two highly successful parts, Don and Don 2, SRK will once again be back in his Don avatar ready to dazzle the audience. Talks of Katrina Kaif replacing Priyanka Chopra in this one have been doing their rounds, nothing has been confirmed yet.Rock On!! 2: Rock On!! was one of the films that completely changed the game in Bollywood. The film was an instant hit among people from all walks of life and was even appreciated critically. With the star studded cast, the film will be back once again and this time including Shraddha Kapoor. The film is apparently set to release in September 2016 but nothing has been announced officially.Housefull 3: With a star studded cast such as Housefull and Housefull 2, it is no surprise that the makers have already begun preparing for the film’s third part. After the first two commercially successful films, Housefull 3 will be back next year set to release on June 3, 2016. This time the film has a special addition that is actor Abhishek Bachchan.Son of Sardar 2: Ajay Devgn’s role as a Sardar in the film Son of Sardar tickled our funny bones for sure. The film went on to collect more than 100 crores which makes it obvious as to why a sequel has been planned. Son of Sardar 2 will be made on public demand and is apparently slated for release during Diwali 2017. Again it might star Sonakshi Sinha.Hera Pheri 3: After the first two highly successful films, makers of Heri Pheri are soon going to be back with its sequel. The film was announced quite a while back but the casting is still under process. Although original actors Akshay Kumar and Suniel Shetty have exited the film so we wonder what the third part would be like. Actor John Abraham has joined the cast.ABCD 3: In the first part there weren’t many big faces except Prabhu Deva, still the film managed to become a super hit blockbuster. After ABCD 2’s success starring Varun Dhawan and Shraddha Kapoor, Remo D’Souza has become confident about making it a film series altogether. We wonder who would be the leads in the third edition of the dance based Bollywood film!Tere Bin Laden Dead or Alive: The underdog film Tere Bin Laden that managed to perform well without any starry cast will be back with its sequel soon. Tere Bin Laden that originally starred actor singer Ali Zafar will be coming out with its sequel Tere Bin Laden Dead or Alive set to release on October 30, 2015. The film will star Manish Paul and Pradhuman Singh.Ghayal Once Again: Sunny Deol’s hit film Ghayal that released in 1990 set a mark for the actor in the industry. Sunny who has been absent from the limelight for quite a while is making a comeback with this film’s sequel, Ghayal Once Again which he has also directed himself. Sunny Deol’s film was supposed to release in November but has been pushed to January 2016.Great Grand Masti: After the two films Masti and Grand Masti, the makers of these two films are back again with Great Grand Masti. Looks like they have no plan of stopping the Masti, as they’ll be back once again this November 2015. With lots of double meaning jokes and confusion based comedy, Riteish Deshmukh, Vivek Oberoi and Aftab Shivadasani will be back once again.Hate Story 3: With the recently released trailer it is pretty sure that this film is much bolder and raunchier than its prequels. After the success of Hate Story 2, director Vishal Pandya has come up with its sensuous thriller sequel Hate Story 3 starring Sharman Joshi, Zareen Khan, Karan Singh Grover and Daisy Shah in the lead roles. The film will be a dirty game of love, revenge, lust and betrayal releasing on December 11, 2015.Kya Kool Hai Hum 3: Now this one we are not vouching for. Agreed that the first part Kya Kool Hai Hum was pretty great, the film’s second edition wasn’t all that good. However the filmmakers are confident about this series and have thus announced the making of its third part. Apparently Riteish Deshmukh has turned it down, but Tusshar Kapoor will still be the lead.
