>> reporter: so it comes down to not just the car, but how you drive that car? >> ken was very easy on the car, miles' crew chief. what was ken miles like? >> to me he was a very, very likable fellow. if you got in any kind of trouble with what you were doing, he show you'd how to handle it and take care of it. he was a great guy. i loved him. >> reporter: what did you love about him? >> he was so friendly and so passionate about everything he did. he was great to be around. >> reporter: what was the dynamic between carroll and ken like? >> unlike the movie, they were quite friends. i never seen them into an argument or anything like that. >> reporter: there were no fistfights? >> i'd never seen any fistfights. >> reporter: and the act, to who had never worked together before, seemed to have captured that chemistry. >> i know your paths crossed over the years, but what did you think about each other? [ laughter ] >> i tell you i think, matt and i have been very short of

crossing paths very close. we've had the same agent for decades. i know you think i'm making this up. i am very grateful to matt because i wouldn't have a career if it wasn't for rosy. there were many roles i was told well, matt doesn't want to do it so they went all right, that failed. >> reporter: kidding aside, damon did turn down the dickey eckeland in "the fighter" a role for which bale took home an oscar award. bale snagging a nomination for his close embodiment of vice president dick cheney. >> fhe heavyweight american vp -- >> nothing in there about my trunk and your lovely little -- >> reporter: christian bale, who is actually british and skinny, had to become british and skinny again. >> you can stick this bloody sticker -- >> hey, hey.

you, but to paraphrase ernest hemingway, all true stories end in death. and "ford versus ferrari" is based on a true story. >> if a movie work, you end up feeling a lot of gratitude for all the people who worked on it because it's hard work. >> reporter: much like putting a ce we're not rking our lives. >> reporter: good point. >> we're lighter. we're faster. when that doesn't work, we're nastier. >> reporter: what is it about this film that you want people to see? >> well, it's a beautiful story and hopefully it's a chance for everybody to kind of come together in a dark movie theater and see a story about friendship. that's a nice thing to put out into the world right now. >> reporter: you could say "ford versus

so-called influencers will have to find another way to show how influential they are.

graham is dropping the famous likes button. jonathan vigliotti shows us why. >> reporter: for users like my mom who only get about five likes per post, i think it's pretty welcome news, but you're right. there is controversy. for one, rapper nicki minaj who is vowing to no longer use the platform, she says among other things actually removing likes takes away power from influencers and emerging artists who want to show how big their fan base. but when you talk to the head of instagram, he says ultimately this is about users' mental health. >> people live for the likes. >> yes. >> are you worried or concerned that will hurt your platform, taking away the likes? >> a little. >> reporter: worried or not, it's happening. making good on a pledge he made to gayle king last june, adam mosseri is changing the way millions of users interact with the app. >> we don't want it to be such a competition. well want it to be a place where people spend more of their energy connecting with the people they love and the things they care about.

gramm experience. >> reporter: lauren says the binary like and dislike is already outdated. mosseri agrees. >> we will do things that mean people use instagram less if we think they keep people safe or generally create a healthier environment. i think we have to be willing to do . >> instagram's new ceoasly healthy community, and i think this is definsiness. >> reporter: and another concern being voiced, this will be the end of instagram influencers, users who profit from having a huge fan base. our expert disagrees. she says instagram has other analytic tools to share with influencers, and losing likes won't change the type of engagement they' already seen. the "overnight news" for this tuesday from the it's tuesday, november 12th, 2019. this is the "cbs morning news."
