I found the movie: Eagle Eye (2008).
https://www.imdb.com/title/tt1059786/plotsummary/?ref_=tt_stry_plThat synopsis does not discuss the CTA 'L'.
Typical plot bit: The president's cabinet is announced and the members begin to file in. The president arrives. Sam's class, whose recital has been moved from the Kennedy Center to the capitol to play the national anthem prior to the president's speech, begins to play. The trigger that will set off the explosive necklace is set to activate when Sam plays a sustained "high F" on his trumpet corresponding to the word "free" in the last stanza of the national anthem. ARIIA had arranged this as poetic justice, believing the president to not be brave. ARIAA is the computer that has taken on regime change as a task.
From an IMDB contributor about the 'L' stations (I misremembered Argyle for Wilson, the two stations on the Red Line are close to each other, but far from downtown).
"Early in the movie when Jerry is on the El train in Chicago, he is shown at the Quincy stop, but the train that he is on is a specific type of train that is only utilized on the Blue line route that doesn't go through the Quincy station. Also, shortly after leaving the Quincy station he is shown at the Wilson station, which is on a completely different train line and would probably require at least 30 minutes to get to even if on the correct train line."
Quincy is a stop on the Loop 'L' for the Brown and Orange Lines. Wilson and Argyle are stops on the Red Line, which is a subway downtown and elevated on the north side.
