Jesse Eisenberg was obsessed with writing sex jokes as a teenager and used to write his gags out on napkins.
Jesse Eisenberg used to write sex jokes on napkins when he was 13 years old.
The 'Double' actor - who is dating actress Mia Wasikowska - thought the gags were great at the time but admits he recently found it funny looking back on them because they are so ''misguided''.
He said: ''[I wrote] a lot of jokes, in fact. And they were all sex-based. I've since revisited them, and looking at them I felt like, 'Clearly, this person will never have sex.' They were just totally misguided.''
Speaking about his thoughts after watching some of their movies, he added: ''I could write stuff like this.''
As well as writing, Jesse has gone on to land the part of Lex Luthor in the hotly-anticipated 'Batman v Superman: Dawn of Justice', and he he is enjoying the chance to appear in a big budget film because he is getting more of a chance to experiment with his character.
He told The Times newspaper: ''In some ways the Batman movie allows me to experiment more with my character because there's a lot more time; in independent movies I can sometimes only do one take of a very interesting scene, but in 'Batman' I can do 40 takes of the one scene just because they plan to spend the whole day on the scene because they have so much money.''
