The 'Gravity' actress is hoping to unite her fellow A-listers to produce the ''mother of all comedies'' to rival hit films such as 'Bridesmaids' and her own film, 'The Heat'.
The trio of actresses are hunting for a script that would give them all a chance to shine, with Bullock spearheading the project.
A source told RadarOnline.com: ''Sandra is the one who is friends with both Cameron and Jennifer, and would likely get top billing in the project.
''It's amazing that this is even being considered by this group -- and shows that they're putting aside old rivalries to find ways of staying relevant in recession-racked Hollywood.
''Although there isn't a script or concept in play just yet, the film could do for girl comedies what 'The Avengers' did for superhero movies.''
It's thought 'The Heat' producer Peter Chernin may come on board for the film, while fellow actress Drew Barrymore has expressed interest in directing.
The comedy would follow the success of Bullock's recent hit 'The Heat', which co-starred Melissa McCarthy and grossed over $200 million worldwide.
The insider added: ''The success of 'The Heat' and the movie 'Bridesmaids' has shown that female buddy comedies are the hottest thing going and Cameron, Sandra and Jen would love to work together and rake in box office gold.''
