Penny’s (the hot girl) on-and-off relationship with Leonard (the nerdy scientist guy), has been a major plot point throughout the series. In addition to the sexy vibe she brings to the show, Penny has moments where she touches the audience with her kindness and thoughtfulness as a friend.
2. By Kaley Cuoco
Kaley Cuoco earns nearly $1 million per episode for her role in The Big Bang Theory and it has seen her become a millionaire, who is now in charge of her own production company. As a multi-talented star, besides her brilliant acting skills, Kaley is an avid equestrian and used to be an accomplished tennis player once upon a time.
3. Howard Wolowitz
Mummy’s boy Howard seems to be the character that goes through the most significant change in the show. All of a sudden, he goes from being the geek who is only interested in women and sex, to a loving and responsible boyfriend, after falling in love with Bernadette. He is now a father of two children and has made a big breakthrough in his career.
4. By Simon Helberg
After his success in the show, Simon had the opportunity to act alongside Hugh Grant and Meryl Streep in the movie Florence Foster Jenkins. Like his character Howard, he also has two children in real life with wife Jocelyn Towne.
5. Sheldon Cooper
As a very talented theoretical physicist with high IQ yet poor social skills, Sheldon has entertained the audience with his quirky, neurotic yet lovable and hilarious character from the very beginning. Since season 5, he has been “romantically” involved with Amy Farrah Fowler and finally proposed to her in season 10. They married in season 11.
6. By Jim Parsons
Although Jim appeared in a few films before, it was The Big Bang Theory that finally turned him into a Hollywood star. He is now one of the highest-paid TV comedy actors, taking home $900,000 for each episode. He came out in 2012 and wedded his partner Todd Spiewak in May 2017 after a 15 year relationship.
7. Leonard Hofstadter
As the best friend of Sheldon Cooper, Leonard gets easily annoyed by his friend’s weird personality, but loves him all the same. Leonard too is completely smitten with his neighbor, Penny, who happens to be way out of his league. After years of ups and downs in their relationship, the experimental physicist finally wedded his goddess in season 9.
8. By John Galecki
John’s acting career didn’t really take off until his casting as Leonard Hofstadter in the show. The character won him an Emmy for Outstanding Lead Actor in a Comedy, as well as an extremely high salary that makes others green with envy - $900,000 per episode.
9. Amy Farrah Fowler
Amy first showed up in the finale of season 3 as Sheldon Cooper’s perfect date, and later became a regular in the show. The neurobiologist likes Sheldon a lot in spite of his bluntness and inability to care about other people’s feelings. She and Sheldon married in season 11 at an intimate wedding ceremony where she gave a very touching vow.
10. By Mayim Bialik
Her character Amy in the show often makes your head spin with her professional terminology, but what you may not know is that Mayim is also a brain in real life and that she earned her Ph.D in neuroscience at UCLA! She’s been signed for the 12th season, but unlike Kaley, Jim and John, Mayim only gets half a million dollars per episode.
11. Bernadette Rostenkowski-Wolowitz
Bernadette is definitely the tough one in the show. The short and squeaky-voiced microbiologist always makes you question yourself with her bitter sarcasm and her ability to get what she wants by bullying people who are much bigger than her. She married Howard, had two children back to back and handles herself very well.
12. By Melissa Rauch
Melissa went through difficulties with her real-life quest for motherhood, as revealed when she shared on social media about her struggles to have a baby and the miscarriage that hit her hard. After her struggles, Melissa and her husband Winston Rauch finally welcomed their baby girl Sadie into the world in December 2017.
13. Rajesh Koothrappali
Here we come to another member of the fun gang - Rajesh, the astrophysicist who is Howard’s best friend. He has trouble talking with women and is majorly obsessed with his kitten. Although he’d been romantically challenged for a while, he moved past that phase finally and had a few different relationships. But, unfortunately he is still a loner in the just-ended 11th season.
14. By Kunal Nayyar
Kunal Nayyar, was born in London and raised in New Delhi, before moving to the US and landing the role of Raj in The Big Bang Theory. He is now on the list of the highest paid TV actors in the world.

15. Stuart Bloom
This lovable loser made his debut in the second season as the owner of the comic book store, which became a regular haunt of the gang. He struggles financially regularly and ends up living with Howard and Bernadette as a babysitter. Recently, his book store business had boomed owing to the celeb effect.
16. By Kevin Sussman
Before playing Stuart in TBBT, Kevin had already made a name for himself in Hollywood. He worked with Spielberg in A.I. Artificial Intelligence in 2001 and played the role of Supernerd. Unlike Stuart in the show, Kevin doesn’t have money issues in real life. Quite the opposite in fact!
17. Emily Sweeney
Emily made her appearance in season 7 as a sweet dermatologist and Raj’s girlfriend in a love triangle. She was totally fine with Raj’s dating another girl Claire while seeing her. Aside from her gorgeous looks, it’s Emily’s dark humor and love for anything horror that Raj finds irresistibly attractive.
18. By Laura Spencer
Laura Spencer is an actress and writer, known for her roles in several hit shows. Unfortunately, if rumors are to be believed, it seems that Laura will not return to the show for a while. So, if you want to see her on TV, her roles in The Lizzie Bennet Diaries, Bones and Sleepy Hollow are definitely worth checking out.
19. Mary Cooper
If anyone could bring our genius Sheldon Cooper into line, it is his dearest mom Mary. Every time Leonard couldn’t handle Sheldon (and it’s a lot), it’s Mary that he always turns to for help. Mary Cooper has appeared on every season of the show so far and is a very fun addition.
