The day of the jackal gay scene explained

You are misremembering what happened. Near the start of the film, the Jackal obtains the Danish passport at Heathrow airport by simple pickpocketing. On his arrival in Paris near the end of the film, is when he pretends to be gay (to trick his way into getting an invite to stay in someone’s house).

The Day of the Jackal came to another tense conclusion in episode 6, when the Jackal found himself in a very different position to where he was just one episode earlier. The Day of the Jackal TV series is a reimagined and updated version of the film and the novel of the same name.
