How about as two aged and lifelong friends, who've just discovered that they both have a terminal condition.
What would it be like to see their story as these two "brothers" face their mortality at the same time.
Not a "Bucket List" bittersweet comedy, but maybe a true character study of two men reflecting back on their failures and triumphs as their days grow shorter, together.
Getting to see two bud's share everything from their love of playing baseball to falling for the same girl to even sharing careers! After Rearing families together, now they get to "cash in" together. I'll bet these two actors would be comfortable enough with each other to bring a reality to that kind of story that could be oscar worthy. People can really underestimate the abilities of these two men... Jus' Sayin'
