( The Frisky ) -- There are certain families -- like , say , the Coppolas and the Gyllenhaals -- where coolness seems to be infused in the DNA . I 'd like to add another to the list : the Reitmans . Papa Ivan is the producer behind flicks like `` Ghostbusters '' and `` Animal House , '' and son Jason grew up on his sets . `` I was on the set of 'Animal House ' when I was 11 days old . It had a profound effect on me , '' Jason joked this week on `` Late Night With Jimmy Fallon . '' When he was in his early teens , Jason started working as a production assistant and his dad even cast him in a few small roles . `` I was 13 and my dad gave me a scene in 'Kindergarten Cop ' kissing a girl -- and that was in fact my first kiss , '' said Jason . `` My first kiss was directed by my father . You do n't know what it 's like to have to do eight takes of your first kiss while Arnold Schwarzenegger 's pointing a gun at you and your dad 's like , 'Grab her a little more . ' '' While Jason probably could have busted into filmmaking by birthright , he decided against directing `` Dude , Where 's My Car ? '' which he was offered , and instead worked on short films to gain clout . `` It 's interesting because I avoided working with my dad for a while because I was so sensitive of being accused of the idea of nepotism , '' he said . `` I remember when I was 19 years old I started a desk calendar company to pay for my first short film just so I could say one day my daddy did n't pay for my first short film . And I really established myself through the film festival world , starting at Sundance and lots of film festivals and really took on a different style of film from my father . '' Soon , Jason directed `` Thank You For Smoking . '' Then the amazingness that was `` Juno . '' And now , of course , he is the Best Director/Best Picture forerunner with his movie `` Up In The Air , '' which is getting all sorts of critical acclaim . `` Up in the Air '' is the first project the two worked on together . `` I love my father and we have such a strong bond and I look up to him as a filmmaker and a storyteller , '' said Jason . `` So it was great and when I see the credits and it says produced by Ivan Reitman and Jason Reitman , my heart swells . It 's really , really cool . '' Ivan echoes that sentiment . `` It 's great to be the producer of this kind of movie and sort of share in its success and the goodwill that comes with it , '' he said . `` But as a parent it 's kind of this remarkable emotional moment that 's kind of hard to describe . '' And it 's not like Ivan 's career is over -- he has a script in the works for `` Ghostbusters 3 '' and the word on the street is that Bill Murray will be making a cameo in it as a ghost himself . Could this family be any cooler ? TM & © 2009 TMV , Inc. | All Rights Reserved .
