It’s probably a bit intimidating for Tom Holland to work with all of these older, famous actors, and while he said they were all welcoming, having someone like Chris Pratt around has to be helpful.
Of course, having Chris Pratt being Chris Pratt while you are trying to act is probably somewhat challenging.
Chris Pratt’s stories about the industry were also probably instructive as Tom Holland sees his own star continuing to rise.
Although it actually makes sense that a teenager like Peter Parker would be quite amused by the ridiculous Star-Lord.
