UPDATE: Fox 411 is reportedly incorrect about this. See an update here.
According to the site, “The Office” star has appeared in front of producers repeatedly since the start of the new year and since rumors began in February:
“John has read 4 times and is doing screen tests,” their source says. “He has screen tested 2 times so far. It’s very likely that he will be the new Captain America. He is a favorite among the key decision makers and has been asked to come back for more this week.”
The source added: “The big bosses are having him read with multiple actresses up for the female leads. They want to lock down the role and then they will narrow down everyone else.”
