Re: Peanuts Movie to Open Against Marvel's Ant-Man!
With a few things present, Antman could do decent numbers.
1)A good script, directer and cast.
2)A cameo in the Avengers 2 that leads up to the solo film.
3)An cameo from one or more of the current Avengers cast.
With all these thing factoring in, the naysayers would be replaced with crickets. As for Fox placing Snoopy on the same date... Perhaps they need some more competition around Marvel films.
The 2-10% they get from Fox for the licensing Marvel films is peanuts (pun intended) So teaching Fox a lesson would be more beneficial I would think.
