A Co-Production can be a huge attachment
A Co-Production isn't new to the history of filmmaking. Over the years, it has evolved becoming an integral part within the business of filmmaking. Basically it brings together different production or distribution entities with a common goal; make a good and of course profitable film.
So it's not uncommon, especially for the major "A" films to have multiple production companies. This can bring in specialities within production companies and help defer some financial risks.
If you notice, sometimes when a marketable "A" talent is attached, the talent's company or the talent themselves will be listed as a co-producer. Their actual duty or responsibility may vary, but they do help get the movie produced.
Producers or distributors working together is also very common for smaller, lower budget films. One producer may not have the financial ability to get a movie into production, but when joined by another producer or a distributor, either attachment might secure the financing.
This also happens with some TV productions. How many times have you seen the lead TV talent listed as Producer or Executive Producer? In the long run, this type of production works best for not only the production but also the talent.
The attached talent helps the production secure financing through their past body of work, their marketability. The talent then receives additional creditability by their involvement in the business side of the production. A win win!
